Target lie near secreting cell​


A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.


The killing of target cells is a complex process that involves the phenotypical and functional activation of NK cells, leading to the secretion of lytic granules containing perforin and granzymes at the immunological synapse
