Constitutive alternative NF-kappaB signaling promotes marginal zone B-cell development but disrupts the marginal sinus and induces HEV-like structures in the spleen.

Abstract excerpt

Nuclear factor-kappaB (NF-kappaB) plays a crucial role in B-cell and lymphoid organ development. Here, we studied the consequences of constitutive, signal-independent activation of the alternative NF-kappaB pathway for the splenic marginal zone (MZ). In contrast to nfkb2(-/-) mice, which lack both p100 and p52, mice that lack only the inhibitory p100 precursor but still express the p52 subunit of NF-kappaB2...
