Comprehensive analysis of lymph node stroma-expressed Ig superfamily members reveals redundant and nonredundant roles for ICAM-1, ICAM-2, and VCAM-1 in lymphocyte homing

Although it is well established that stromal intercellular adhesion molecule-1 (ICAM-1), ICAM-2, and vascular cell adhesion molecule-1 (VCAM-1) mediate lymphocyte recruitment into peripheral lymph nodes (PLNs), their precise contributions to the individual steps of the lymphocyte homing cascade are not known. Here, we provide in vivo evidence for a selective function for ICAM-1 > ICAM-2 > VCAM-1 in lymphocyte arrest within noninflamed PLN microvessels. Blocking all 3 CAMs completely inhibited lymphocyte adhesion within PLN high endothelial venules (HEVs). Post-arrest extravasation of T cells was a 3-step process, with optional ICAM-1-dependent intraluminal crawling followed by rapid ICAM-1- or ICAM-2-independent diapedesis and perivascular trapping. Parenchymal motility of lymphocytes was modestly reduced in the absence of ICAM-1, while ICAM-2 and alpha4-integrin ligands were not required for B-cell motility within follicles. Our findings highlight nonredundant functions for stromal Ig family CAMs in shear-resistant lymphocyte adhesion in steady-state HEVs, a unique role for ICAM-1 in intraluminal lymphocyte crawling but redundant roles for ICAM-1 and ICAM-2 in lymphocyte diapedesis and interstitial motility.

The prevalence of vitamin D inadequacy amongst women with osteoporosis: an international epidemiological investigation

INTRODUCTION: Vitamin D is essential for calcium metabolism as well as for fracture prevention, and a recent review suggested that the optimal serum 25(OH)D lies in the region of 50-80 nmol L-1 (20-32 ng mL-1). A high prevalence of inadequacy has been reported in many studies but the prevalence of inadequacy amongst women with osteoporosis in different regions of the world has not been well characterized. SETTING AND SUBJECTS: A multinational study of 18 countries at various latitudes (range 64N-38S) was conducted in 2004 and 2005 to determine the average levels of serum 25(OH)D and the prevalence of vitamin D inadequacy. A total of 2606 postmenopausal women with osteoporosis (low bone mineral density, history of fragility fracture) seeking routine medical care were enrolled and serum 25(OH)D levels were measured at a single laboratory visit. RESULTS: Mean serum 25(OH)D level was 26.8 ng mL-1 (SE 0.3) and ranged from 7 to 243 ng mL-1. Regional mean values were highest in Latin America (29.6 ng mL-1, SE 0.6) and lowest in the Middle East (20.4 ng mL-1, SE 0.5). Overall, 64% of women had serum levels<30 ng mL-1. Serum parathyroid hormone reached a nadir at serum 25(OH)D levels>35 ng mL-1. In nonequatorial countries, women recruited during the winter months had somewhat lower serum 25(OH)D levels than those recruited during the summer months in some, but not all, countries. CONCLUSIONS: Low levels of serum 25(OH)D are common amongst women with osteoporosis. The results underscore the value of assuring vitamin D adequacy in these women.

Effect of disodium monofluorophosphate, calcium and vitamin D supplementation on bone mineral density in patients chronically treated with glucocorticosteroids: a prospective, randomized, double-blind study

To study the effect of fluoride on bone mineral density (BMD) in patients treated chronically with glucocorticosteroids, 15 subjects (renal grafted, n = 12; skin disease, n = 1; broncho pulmonary disorder, n = 1; Crohn's disease, n = 1) were prospectively studied in a double-blinded manner and randomly allocated either to group 1 (n = 8) receiving 13.2 mg/day fluoride given as disodium monofluorophosphate (MFP) supplemented with calcium (1,000 mg/day) and 25-hydroxyvitamin D (calcifediol) (50 micrograms/day), or to group 2 (n = 7) receiving Cas+ calcifediol alone. An additional group of 14 renal transplant patients treated chronically with glucocorticosteroids but exempt of specific therapeutic intervention for bone disease was set up as historical controls. BMD was measured by dual-energy X-ray absorptiometry (DXA, Hologic QDR 1000) performed at months 0, 6 and 12 for groups 1 and 2 (lumbar spine, total upper femur, diaphysis and epiphysis of distal tibia), or 11-31 months apart with calculation of linear yearly changes for the historical cohort. Lumbar BMD tended to rise in groups 1 and 2, and to fall in group 3, the change reaching statistical significance (p < 0.05) in group 1, thus leading to a significant difference between groups 1 and 3 (p < 0.05). At upper femur, tibial diaphysis and tibial epiphysis, no significant change in BMD occurred in any of the groups. In conclusion, lumbar BMD rises more after a mild dosis of fluoride given as MFP and combined to calcium and calcifediol than on Ca+ calcifediol alone, without changes in BMD at the upper femur or distal tibia.

Identification of two vitamin D response elements in the rat osteopontin gene

Studies to elucidate the function of vitamin D have demonstrated an important role in regulating bone-related cells, including osteoblasts and osteoclasts. A seemingly paradoxical observation is that 1,25(OH)$\sb2$D$\sb3$, the active metabolite of vitamin D, stimulates bone resorption, yet regulates transcription of genes expressed by osteoblasts. One mechanism that could explain these actions is the upregulation of transcription of osteoblast-specific genes. These gene products could then act as effectors to influence osteoclastic activity. We hypothesized that molecular signals could be deposited directly into the mineralized matrix in the form of noncollagenous proteins, such as osteopontin (OPN). The structure, biosynthesis and localization of OPN suggest that it could function to mediate the molecular "cross talk" between osteoblasts and osteoclasts in response to 1,25(OH)$\sb2$D$\sb3$. To begin to address this hypothesis, elucidation of the molecular mechanisms of action involved in the transactivation of OPN by 1,25(OH)$\sb2$D$\sb3$ is essential.^ In the present study, the rat opn gene was isolated and characterized. Functional analysis by transient transfection of the 5$\sp\prime$ flanking sequences of the rat opn gene fused to the luciferase gene demonstrated that OPN is transcriptionally upregulated by 1,25(OH)$\sb2$D$\sb3$, mediated through two vitamin D response elements (VDRE). Both proximal and distal VDREs are structurally similar (two imperfect direct repeats separated by a 3 nucleotide spacer) and bind protein complexes that include the VDR and retinoid-X receptor (RXR). Isolated VDRE expression constructs produce functional activity of equivalent magnitude of responsiveness to 1,25(OH)$\sb2$D$\sb3$. However, expression constructs containing either VDRE and at least 200 bp of 5$\sp\prime$ and 3$\sp\prime$ flanking sequence demonstrated that the distal VDRE produces an amplitude of response significantly higher than the proximal VDRE. We conclude that the transcriptional upregulation of the opn gene by 1,25(OH)$\sb2$D$\sb3$ involves the transactivation of two VDREs, while maximal responsiveness requires interaction of the VDREs with additional cis-elements contained in the 5$\sp\prime$ sequence. ^

Vitamin D time profile based on the contribution of non-genetic and genetic factors in HIV-infected individuals of European ancestry

BACKGROUND Vitamin D deficiency is prevalent in HIV-infected individuals and vitamin D supplementation is proposed according to standard care. This study aimed at characterizing the kinetics of 25(OH)D in a cohort of HIV-infected individuals of European ancestry to better define the influence of genetic and non-genetic factors on 25(OH)D levels. These data were used for the optimization of vitamin D supplementation in order to reach therapeutic targets. METHODS 1,397 25(OH)D plasma levels and relevant clinical information were collected in 664 participants during medical routine follow up visits. They were genotyped for 7 SNPs in 4 genes known to be associated with 25(OH)D levels. 25(OH)D concentrations were analyzed using a population pharmacokinetic approach. The percentage of individuals with 25(OH)D concentrations within the recommended range of 20-40ng/ml during 12 months of follow up and several dosage regimens were evaluated by simulation. RESULTS A one-compartment model with linear absorption and elimination was used to describe 25(OH)D pharmacokinetics, while integrating endogenous baseline plasma concentrations. Covariate analyses confirmed the effect of seasonality, body mass index, smoking habits, the analytical method, darunavir/r and the genetic variant in GC (rs2282679) on 25(OH)D concentrations. 11% of the interindividual variability in 25(OH)D levels was explained by seasonality and other non-genetic covariates and 1% by genetics. The optimal supplementation for severe vitamin D deficient patients was 300000 IU two times per year. CONCLUSIONS This analysis allowed identifying factors associated with 25(OH)D plasma levels in HIV-infected individuals. Improvement of dosage regimen and timing of vitamin D supplementation is proposed based on those results.

Low-frequency drug-resistant HIV-1 and risk of virological failure to first-line NNRTI-based ART: a multicohort European case-control study using centralized ultrasensitive 454 pyrosequencing.

OBJECTIVES It is still debated if pre-existing minority drug-resistant HIV-1 variants (MVs) affect the virological outcomes of first-line NNRTI-containing ART. METHODS This Europe-wide case-control study included ART-naive subjects infected with drug-susceptible HIV-1 as revealed by population sequencing, who achieved virological suppression on first-line ART including one NNRTI. Cases experienced virological failure and controls were subjects from the same cohort whose viraemia remained suppressed at a matched time since initiation of ART. Blinded, centralized 454 pyrosequencing with parallel bioinformatic analysis in two laboratories was used to identify MVs in the 1%-25% frequency range. ORs of virological failure according to MV detection were estimated by logistic regression. RESULTS Two hundred and sixty samples (76 cases and 184 controls), mostly subtype B (73.5%), were used for the analysis. Identical MVs were detected in the two laboratories. 31.6% of cases and 16.8% of controls harboured pre-existing MVs. Detection of at least one MV versus no MVs was associated with an increased risk of virological failure (OR = 2.75, 95% CI = 1.35-5.60, P = 0.005); similar associations were observed for at least one MV versus no NRTI MVs (OR = 2.27, 95% CI = 0.76-6.77, P = 0.140) and at least one MV versus no NNRTI MVs (OR = 2.41, 95% CI = 1.12-5.18, P = 0.024). A dose-effect relationship between virological failure and mutational load was found. CONCLUSIONS Pre-existing MVs more than double the risk of virological failure to first-line NNRTI-based ART.

Reversible accumulation of (1→3,1→4)‐β‐glucan endohydrolase in wheat leaves under sugar depletion

A (1→3,1→4)‐β‐D‐glucan endohydrolase [(1→3,1→4)‐β‐glucanase, EC 3.2.1.73] was detected in wheat (Triticum aestivum L.) leaves by Western analyses and activity measurements. This enzyme is able to degrade the (1→3,1→4)‐β‐glucans present in the cell walls of cereals and other grass species. In wheat, enzyme levels clearly increased during leaf development, reaching maximum values at full expansion and then decreasing upon leaf ageing. To test whether the abundance of (1→3,1→4)‐β‐glucanase might be controlled by the carbohydrate status, environmental and nutritional conditions capable of altering the leaf soluble sugar contents were used. Both the activity and enzyme protein levels rapidly and markedly increased when mature leaves were depleted of sugars (e.g. during extended dark periods), whereas elevated carbohydrate contents (e.g. following continuous illumination, glucose supply in the dark or nitrogen deficiency during a light/dark cycle) caused a rapid decrease in (1→3,1→4)‐β‐glucanase abundance or prevented its accumulation in the leaves. The physiological significance of (1→3,1→4)‐β‐glucanase accumulation under sugar depletion remains to be elucidated.

New insights into the role of the duodenal vitamin D receptor in calcium homeostasis

It is generally believed that 1,25(OH)2D3, bound to its receptor (VDR) contributes to calcium homeostasis by regulating active calcium absorption in the proximal small intestine. However, studying patients with hereditary vitamin D-resistant rickets (HVDRR) provided investigators with a better understanding of VDR's role in calcium homeostasis. HVDRR patients have inactivating mutations in the VDR, and as a consequence they develop hypocalcemia, hyperparathyroidism and severe rickets. However, these phenotypes can be corrected if the patients are given IV infusions of calcium or dietary calcium. This raises the question of what is the physiological significance of VDR-regulated active calcium absorption if calcium homeostasis can be restored independently of the VDR. ^ In order to distinguish the contribution of VDR in the proximal small intestine to overall calcium homeostasis, I generated transgenic mice expressing the human VDR (hVDR) exclusively in the proximal small intestine of mVDR-/- mice by using an hVDR-expressing transgene driven by the duodenal-specific adenosine deaminase enhancer (hVDR+/mVDR-/-). hVDR+/mVDR-/- mice expressed transcriptionally active hVDR only in the proximal small intestine and responded to 1,25(OH)2D3 by up-regulating expression of TRPV6 and calbindin D9K, genes involved in calcium absorption. Furthermore, ligated duodenal loop assays determined that calcium absorption in hVDR+/mVDR-/- mice was as responsive to 1,25(OH)2D3 as in WT mice. Despite having a functional hVDR in the proximal small intestine, hVDR+/mVDR-/- mice were hypocalcemic, had hyperparathyroidism, and were rachitic when fed a normal rodent diet at weaning, as were the mVDR-/- mice. However, when fed a high calcium, phosphorus, and lactose diet (rescue diet), the hVDR+/mVDR-/- mice responded more effectively than the mVDR-/- mice by down-regulation of parathyroid hormone production and by a greater increase in bone mineralization. Furthermore, when three-month-old rachitic mice were fed a rescue diet for 3 weeks, serum calcium and bone mineral content were normalized in hVDR+/mVDR-/- mice, but not in mVDR-/- mice. ^ In conclusion, hVDR expression enabled young mice to better use the rescue diet than mVDR-/- mice. Expression of transgenic hVDR also protected the ability of older mice to respond to the rescue diet despite the absence of the VDR elsewhere in the intestinal tract. I propose that because hVDR+/mVDR-/- mice responded better than mVDR-/- mice to the rescue diet, it is likely that VDR expression in the proximal small intestine is necessary in nutritional (insufficient dietary calcium) and physiological (age) conditions when passive calcium absorption is inadequate. ^
