Question

T-cells in lymph nodes ______.

विकल्प

• occur predominantly in the medullary region

• are only of the cytotoxic type

• are phagocytic

• are absent in Di George syndrome

Answer 1

T-cells in lymph nodes are absent in Di George syndrome.

Explanation:

In Di George syndrome, the thymus fails to develop properly, so T-cells do not mature and are absent in lymph nodes. This leads to defective cell-mediated immunity in affected individuals.
