2 Figure 1 BAFF and antigen-driven B cell activation. In cGVHD, B cells are promoted by antigen and excessive BAFF levels to survive and produce antibodies. Constitutive antibody production by certain B cell subsets in cGVHD may directly mediate pathology. B cells may also serve as antigen presenting cells (APC).

3 Figure 2 Development and persistence of potentially pathological cGVHD B cells. Altered B cell homeostasis with high BAFF to naïve B cell ratios after HCT leads to persistence of aberrantly activated B cells. Decreased bone marrow output and production of immature (and potentially of B10) B cells leads to excessive levels of BAFF, sufficient to support potentially pathological B cell subsets.
