Question

Match the cytokine to its description.

Secreted by active T cells and natural killer cells, this cytokine inhibits viral replication, enhances phagocytosis in macrophages, boosts production of antibodies by B cells, and activates both natural killer cells and cytotoxic T cells.

A) interleukin-5
B) interleukin-10
C) interleukin-1
D) interferon-γ
E) interferon-α
F) interleukin-4
G) interleukin-2

Answer 1

The correct cytokine that is secreted by active T cells and natural killer cells to perform functions such as inhibiting viral replication and activating immune cells is interferon-γ.

Step-by-step explanation:

The cytokine described in the question is secreted by active T cells and natural killer (NK) cells, inhibits viral replication, enhances phagocytosis in macrophages, boosts the production of antibodies by B cells, and activates both NK cells and cytotoxic T cells. The correct match for this cytokine, based on its functions, is interferon-γ (interferon-gamma). Interferon-γ plays important roles in immune responses, including antiviral actions and the activation of different immune cells.

It inhibits viral replication, enhances phagocytosis in macrophages, boosts production of antibodies by B cells, and activates both natural killer cells and cytotoxic T cells.
