Fig. 2From: The role of follicular helper CD4 T cells in the development of HIV-1 specific broadly neutralizing antibody responsesConvergence of CD4+ T cells, B cells and FDC in a B cell follicle. Confocal imaging microscopy showing the convergence of immune populations contributing to the development of bnAbs in a lymph node B cell follicle derived from a HIV- individual. CD4 T cells are shown in green, CD20 in blue and FDCs in red. Images were acquired at ×40 (NA 1.3). Captions are a 50 μm and b15 μm respectivelyBack to article page
