Question

Quizplus · Accepted Answer

NK cells, or natural killer cells, are lymphocyte-like cells that actively search for and destroy abnormal cells, such as cancer cells or virus-infected cells. They are an important part of the immune system's overall surveillance for potentially harmful cells. Plasma cells are involved in antibody production, while B and T lymphocytes play important roles in adaptive immunity. Helper T cells help activate and coordinate immune responses, while suppressor T cells help regulate and suppress immune responses to prevent excessive inflammation or damage to healthy tissues.
