Figure 2. Signals to and from Tfh cells.

Figure 2.

Tfh cells receive signals from a number of cell types that can regulate Tfh differentiation and/or function. Tfh cells function by providing help to B cells at a series of stages of antigen-specific B cell differentiation. BAct, activated B cells. BGC, GC B cells. BPC, PC. Bpb, plasmablasts. BMem, memory B cells.
