Periarteriolar lymphoid sheath (PALS) are populated mainly by
Solution
Periarteriolar lymphoid sheaths (PALS) are primarily populated by T lymphocytes. These are a type of white blood cell that play a central role in cell-mediated immunity. They are called periarteriolar because they surround the arterioles, or small branches of arteries, within the spleen. The PALS is a crucial area for the activation of T cells in response to blood-borne antigens.
