since lyb 8 is found on pre-b cells and since it has no demonstrable function in b cell activation , its current role is as an early marker that signifies commitment of stem cells to the b cell lineage . m-anti-lyb 2 antibodies inhibit in vitro antibody responses to srbc and ti-2 antigens but not to ti-1 antigens , m-anti-lyb 2 induces b cell proliferation only in the lyb 5+ subset of b cells .
