Dear Amol, The answer is yes. Lymphocytes have been cultured for more than 30 years now. These cells have a important capability of proliferation, which is one of the basis of the immunological theory. In last years with a better understanding of the stem cell biology, this notion that differentiated cells are unable to replicate has losen its strenght. Foor example, even in the brain, which the cells, the neurons, were thought not to proliferate after embrionary period. Today we know that certain cells, known as neuronal progenitors, are capable of replication and renewal of neuron populations under certain situations. So, cells are much more flexible than we thought before. If I understood right, your second question is: Which cells are infected by HIV besides T CD4 lymphocytes? HIV attaches himself to a complex of molecules in membranes, whose the main one is the CD4 molecule. This molecule can be found in monocytes, macrophages and endothelial cells. Therefore, the cells also can be infected by HIV. Hope all is clear and never hesitate in asking. Best regards, Vitor
