Question

A cell bearing CD8 on its surface would be most similar to or have the most in common with which of the following cells?

Question 8 options:

follicular dendritic cells

NK cells

monocytes

macrophages

dendritic cells

Answer 1

Option). NK cells.

Step-by-step explanation:

Cluster of differentiation 8 (CD8) can bed defined as a transmembrane glycoprotein that acts a co-receptor for the receptor present on T cells (TCR). The CD8 is marker for
`T_c` cells (cytotoxic T cells) as it is predominantly present on cell surface of these cells.

Along with cytotoxic cells, CD8 molecule is also expressed in surface of natural killer cells (NK cells), thymocytes, and myeloid dendritic cells.

Hence, a cell having CD8 on its surface (cytotoxic T cell) would be most similar to NK cells.
