Question

Quizplus · Accepted Answer

Chemokines are chemotactic factors that signal leukocytes to migrate towards a site of inflammation or infection. They do not ensure production of leukocytes or directly play a role in B lymphocyte activation and differentiation. While they may attract basophils and eosinophils to a site, they do not cause degranulation. They are used to signal between leukocytes in the process of chemotaxis.
