Dendritic cells are unique heterogenous cell population capable of responding to different inflammatory signals. These signals induce the process of maturation forcing cells to leave the inflamed site and to migrate to draining lymph nodes. During this process, dendritic cells have to initiate differentiation responses expressed among others by up-regulation of some surface antigens (e.g., MHC ...

Calcium-calmodulin-dependent protein kinase II (CaMKII) promotes the maturation of retinotectal glutamatergic synapses in Xenopus. Whether CaMKII activity also controls morphological maturation of optic tectal neurons was tested using in vivo time-lapse imaging of single neurons over periods of up to 5 days. Dendritic arbor elaboration slows with maturation, in correlation with the onset of CaM...

Early postnatal developmental changes in N-methyl-d-aspartate (NMDA) receptor (NR) subunits regulate cerebellar granule cell maturation and potentially Purkinje cell development. We therefore investigated Purkinje cell morphology in slice cultures from mice with genetic subunit exchange from NR2C to NR2B (NR2C-2B). NR2C-2B Purkinje cells after 12 days in vitro showed a significantly impaired de...

hla-g is normally expressed on human trophoblast cells. it is a non-classical mhc molecule class i b. the role of hla-g in diabetic type 1 is not known. we investigated the role of ifn-β in induction hla-g expression on the monocyte derived dendritic cells (dc) in diabetes type 1. treatment of dendritic cell with ifn-β in vitro from diabetic patients (n=20) and normal subjects (n=20) resulted t...
