CD2 is a cell adhesion molecule found mainly on the surface of T cells and which other type of cell?

CD2 is primarily recognized as a cell adhesion molecule predominantly expressed on T cells, playing a crucial role in their activation and interaction with other cells during the immune response. Natural killer (NK) cells also express CD2, making them significant participants in the immune system alongside T cells.

In the context of the immune response, the presence of CD2 on natural killer cells facilitates their function and enhances their ability to recognize and eliminate infected or transformed cells. The interaction between CD2 on NK cells and its ligands aids in the regulation of cellular responses and promotes the cytotoxic activities of NK cells, similar to its role in T cells.

The other cell types listed do not share the same level of expression of CD2. While B cells, monocytes, and neutrophils have distinct roles in the immune system, they are not primarily characterized by the presence of CD2 on their surfaces, differentiating their functions and interactions from those of T and NK cells.
