RGC-32 as a key regulator of Th17 cell differentiation Using an RGC-32 knock-out (KO) mouse model, we have been able to demonstrate that RGC-32 promotes the differentiation of Th17 cells both in vitro and in vivo. When compared to wild-type (WT) cells, CD4+ cells isolated from RGC-32 KO mice express lower levels of IL-17, as well as some of the transcription factors necessary for Th17 differentiation, including retinoic acid receptor-related orphan receptor gamma t (RORgt), B cell–ac...

Neurons - Individual cells in the nervous system that receive, integrate, and transmit information. glia cells (glia) - help the neurons by nourishing, insulating, replenishing, and modulating them Astrocytes (type of glial cell) - Provide structural and metabolic support for neurons. Astrocytes are large glial cells with round or radially symmetrical forms; they surround neurons and are in close contact with the brain's vasculature. An astrocyte makes contact with blood vessels at special...
