Affirmative Action in Iowa, September 2003

This report is prepared pursuant to Iowa Code Section 19B.5. This Section required The Department of Administrative Services shall submit a report on the condition of affirmative action, diversity, and multicultural programs in state agencies covered by subsection 1 by September 30 of each year to the governor and the general assembly. Subsection 1 requires the head of each state agency to submit annual report of the affirmative action accomplishments of that agency to the Department of Administrative services.

The E3 ubiquitin ligase Itch regulates sorting nexin 9 through an unconventional substrate recognition domain.

The level of intracellular proteins is mainly regulated through modifications by ubiquitin ligases that target them for degradation. Members of the NEDD4 family of E3 ubiquitin ligases, such as Itch (atrophin-1 interacting protein 4), possess up to four WW domains for specific association with PY motif-containing substrates. We have identified sorting nexin 9 (SNX9), a protein involved in endocytic processes, as a new substrate of Itch. Itch ubiquitylates SNX9 and regulates intracellular SNX9 levels. Using truncated proteins, we found that the interaction with SNX9 is mediated by the proline-rich domain (PRD) of Itch, a domain distinct from the conventional WW recognition domain, and the SH3 domain of SNX9. Interaction with the PRD of Itch is essential for SNX9 ubiquitylation and degradation. Furthermore, this effect is specific for Itch, as NEDD4, a related PRD-containing E3 ligase, does not bind SNX9. SNX18, a second member of the SNX family containing an SH3 domain, was also found to bind to Itch. Our results indicate that the pool of substrates of NEDD4 family E3 ubiquitin ligases extends beyond proteins containing PY motifs.

Diagnòstic en profunditat sobre la integració dels i les joves de 14 i 18 anys migrats a Catalunya

La finalitat d'aquest projecte és aprofundir en el procés d'integració socioeducativa de la joventut migrada a Catalunya, específicament, dels i les joves entre 14 i 18 anys. Entre els resultats destaquem que els ioves tenen un concepte força tancat i excloent del concepte de ciutadania com a estatus , i un baix grau, de coneixement de la diversitat cultural, especialment els joves autòctons, tot i que tenen una actitud de reconeixement i acceptació, favorable a la convivència intercultural, tant al centre educatiu com al seu barri. No obstant, tenen una visió de la diversitat cultural i del fet migratori en clau de coexistència, sense el reconeixement que suposaria un pas més cap a la convivència. La immigració és vista com un col•lectiu vulnerable, amb un baix nivell econòmic i cultural i que també és percebut com un problema i, fins i tot, com a causant de les dificultutats que actualment pateix i travessa el conjunt de la societat. Els joves tendeixen a relacionar-se amb el seu grup cultural, i responen de forma passiva en la comprensió i actuació davant dels problemes i assumptes públics. Entre els elements que valoren per sentir-se ciutadà té una especial importància la llengua. Eis joves que fa més de 10 anys que viuen a Catalunya són els que tendeixen a tenir un sentiment de pertinença cívica amb el lloc de residència. De fet, com mes temps porten els joves estrangers vivint al lloc d’acollida, perden importància elements d’identificació cultural del país d’origen, però la religió, les celebracions populars, l’art i la tendència a formar parella són elements identitaris del lloc d’origen, més estables. Es demana una intervenció urgent en diversos nivells i destinades a diferents agents. Destaquem: la importància d’una acollida afectiva i efectiva; potenciar espais de trobada; treballar els prejudicis; transversalitzar l’educació intercultural; potenciació de l’aprenentatge de la llengua catalana; formació del professorat en competències interculturals.

Haemorrhage into the pancreatic duct (Hemosuccus pancreaticus): recognition and management.

OBJECTIVE: To highlight the clinical presentation, investigation and treatment of haemorrhage into the pancreatic duct. DESIGN: Retrospective study and review of publications. SETTING: University hospital, Switzerland. SUBJECTS: All 4 cases from 1972 to 1993. INTERVENTIONS: 2 Whipple procedures, 1 resection of the pancreatic head, 1 exploratory laparotomy. Radiological embolisation in one case. MAIN OUTCOME MEASURES: Cessation of haemorrhage and survival. RESULTS: The diagnosis was made preoperatively in three cases by gastroduodenoscopy and arteriography. Operation was the primary treatment in all patients and was effective with low morbidity and no mortality in three of them. Embolisation stopped the haemorrhage in the fourth patient, who was alcoholic and died of progressive liver insufficiency and variceal haemorrhage. CONCLUSIONS: There is no specific indication for haemorrhage into the pancreatic duct. The diagnosis is suggested by endoscopy (absence of a more common cause, or blood in the second part of the duodenum). Arteriography is essential to confirm the site of the bleeding and to attempt embolization. Operation is usually the definitive treatment.

Species-Specific Recognition of Aspergillus fumigatus by Toll-like Receptor 1 and Toll-like Receptor 6.

Background. Aspergillus fumigatus causes invasive aspergillosis, a potentially fatal infection in oncohematological patients. Innate immune detection of A. fumigatus involves Toll-like receptor (TLR) 4 and TLR2, which forms a heterodimer with either TLR1 or TLR6. The role of those coreceptors in Aspergillus sensing is unknown. Methods. Cytokine production was measured in bone marrow-derived macrophages (BMDMs) from wild-type (WT) and TLR-deficient mice after incubation with a WT and an immunogenic RodA-deficient (ΔrodA-47) strain of A. fumigatus and in lungs from these mice after intranasal mold inoculation. Aspergillus fumigatus-mediated NF-κB activation was measured in HEK293T cells transfected with plasmids expressing mouse or human TLRs. Results. Bone marrow-derived macrophages from TLR1- and TLR6-deficient mice produced lower amounts of interleukin 12p40, CXCL2, interleukin 6, and tumor necrosis factor α than BMDMs from WT mice after stimulation with A. fumigatus. Lungs from TLR1- and TLR6-deficient mice had diminished CXCL1 and CXCL2 production and increased fungal burden after intranasal inoculation of ΔrodA A. fumigatus compared with lungs from WT mice. ΔrodA strain-mediated NF-κB activation was observed in HEK293T cells expressing mouse TLR2/1, mouse TLR2/6, and human TLR2/1 but not human TLR2/6. Conclusions. Innate immune detection of A. fumigatus is mediated by TLR4 and TLR2 together with TLR1 or TLR6 in mice and TLR1 but not TLR6 in humans.

Lack of tumor recognition by hTERT peptide 540-548-specific CD8(+) T cells from melanoma patients reveals inefficient antigen processing.

Telomerase is a ribonucleoprotein complex responsible for the maintenance of the length of the telomeres during cell division, which is active in germ-line cells as well as in the vast majority of tumors but not in most normal tissues. The wide expression of the human telomerase catalytic subunit (hTERT) in tumors makes it an interesting candidate vaccine for cancer. hTERT-derived peptide 540-548 (hTERT(540)) has been recently shown to be recognized in an HLA-A*0201-restricted fashion by T cell lines derived from peptide-stimulated peripheral blood mononuclear cells (PBMC) from healthy donors. As a first step to the inclusion of this peptide in immunotherapy clinical trials, it is crucial to assess hTERT(540)-specific T cell reactivity in cancer patients as well as the ability of hTERT-specific CD8(+) T lymphocytes to recognize and lyse hTERT-expressing target cells. Here, we have analyzed the CD8(+) T cell response to peptide hTERT(540) in HLA-A*0201 melanoma patients by using fluorescent HLA-A*0201/hTERT(540) peptide tetramers. HLA-A*0201/hTERT(540) tetramer(+) CD8(+) T cells were readily detected in peptide-stimulated PBMC from a significant proportion of patients and could be isolated by tetramer-guided cell sorting. hTERT(540)-specific CD8(+) T cells were able to specifically recognize HLA-A*0201 cells either pulsed with peptide or transiently transfected with a minigene encoding the minimal epitope. In contrast, they failed to recognize hTERT-expressing HLA-A*0201(+) target cells. Furthermore, in vitro proteasome digestion studies revealed inadequate hTERT processing. Altogether, these results raise questions on the use of hTERT(540) peptide for cancer immunotherapy.
