Figure 1 Model of antibody-mediated inflammation driving early skin carcinogenesis Naive B cells are activated by skin-derived antigens (HPV16 E6, E7, and/or degraded products of keratinocytes and extracellular matrix?) in the presence of CD4 T cells, and differentiate into memory B cells and plasma cells. Antibodies produced by plasma cells stimulate resident myeloid cells (e.g., macrophages) in the dermis via activating Fc receptors to secrete VEGF, MMPs, and other inflammatory mediators, followed by further recruitment of innate immune cells. Chronic inflammation mediated by interaction of antibodies with innate immune cells facilitates cancer development.
