Furin deficiency efect on T cells

ABSTRACT: Analysis of T-cells lacking the proprotein convertase furin. Proprotein convertases promote the proteolytic maturation of proproteins. Furin is induced in activated T-cells. Results provide insight into the function of furin in T-cells. CD4+CD62L+CD44- naive, CD4+CD62L-CD44+ memory and CD4+CD25+FoxP3+ regulatory T cells were isolated from Fur flox/flox and CD4 cre Fur flox/flox mice. Naive T cells were activated via TCR. Total RNA was extracted from all cells and hybridized to Affymetrix microarrays.

Antigen emergence rapidly stimulates T cells, which leads to changes in cytokine production, cell proliferation, and differentiation. Some of the key molecules involved in these events, such as TGF-β1 and NOTCH1, are synthesized initially as inactive precursors and are proteolytically activated during T cell activation. PCSKs regulate proprotein maturation by catalyzing the proteolytic cleavage of their substrates. The prototype PCSK FURIN is induced upon TCR activation, and its expression in T  ...[more]
