The T cell is a lymphocyte or type of white blood cell. They play a role in the immunity of the body. There are different varieties of T cells and they are differentiated by the receptors that are on the surface of the cells. Some cells are natural killers and some are B cells.
Answer:
Neurons communicate with each other by synapses
Explanation:
Neurons send signals to other neurons through synapses. The most common type is chemical synapse; a chemical synapse occurs between the axon terminal of the neuron that sends the message and the dendrite of the neuron that receives the message. The first one is known as the presynaptic cell and the last one is known as the postsynaptic cell. Moreover, in a chemical synapse, the presynaptic and postsynaptic cells don’t touch each other as they are separated by a very tiny gap known as a synaptic cleft. The chemical synapse transforms an electrical signal (which is the action potential in the presynaptic cell’s axon) into a chemical signal (which is the neurotransmitter) and back to an electrical signal (the postsynaptic potential) in the postsynaptic cell.

I am almost certain that this is correct, hope it helps
i think what you are describing is a cell surface marker
hope this helps ;D
