Dendritic cells play a central role in the regulation of immunological reactivity. The existence of functionally specialized populations of dendritic cells in the skin is a consequence of qualitatively different attacks on our organism. slanDCs are human inflammatory dendritic cells that are characterized by the specific expression of the carbohydrate 6-sulfo LacNAc (slan). After phenotypic maturation, slanDCs are capable of producing very high amounts of proinflammatory mediators such as IL-12, TNF-, IL-1 and IL-23. Recent data describe a potential role of slanDCs in a number of different diseases like psoriasis, lupus erythematosus, and tumors, thus opening up new areas of research on their respective pathogenesis. Furthermore, a slanDC-specific targeting system has been developed as a basis for direct therapeutic manipulation. Future challenges of slanDC research include deepening our understanding of the significance of slanDCs in the regulation of adaptive and innate immune responses, as well as translating this knowledge into therapeutic options.

Protocylindrocorpus brasiliensis n. sp. (Diplogastroidea: Cylindrocorporidae) is described from reproductive stages removed from galleries of the ambrosia beetle, Euplatypus parallelus (F.) (Curculionidae: Platypodinae) in Para rubber trees (Hevea brasiliensis) in Brazil. This is the first record of the genus Protocylindrocorpus from the Neotropics. Males of P. brasiliensis are quite striking because their long spicules extend up to 72% of their total body length. The adults exhibit conspecific agglutination where they congregate in a slimy substance that serves to maintain them in a coherent group for mating. Some of the adults were infected by fungal and protozoan pathogens, implying that disease plays a role in regulating natural populations. The discovery of P. brasiliensis provides new information on nematode structure, behavior, and ecology.
