claimVitamin C stimulates the production and function of leukocytes (white blood cells), specifically neutrophils, lymphocytes, and phagocytes.
claimMacrophages are specialized leukocytes that respond to invading pathogens by initiating phagocytosis and synthesizing and releasing pro-inflammatory cytokines.
referenceA 1977 study by Shilotri PG and Bhat KS published in the American Journal of Clinical Nutrition investigated the effect of megadoses of vitamin C on the bactericidal activity of leukocytes.
claimVitamin C protects leukocytes from autooxidation damage caused by the reactive oxygen species they release.
claimSome studies have reported no beneficial changes in leukocyte production or function following vitamin C treatment.
Chronic Inflammation - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 4 facts
claimUpon activation, leukocytes release additional cytokines and mediators of inflammation.
claimThe cytokines IL-1 and TNF-α induce injury-site endothelial cells to release Selectins and Integrins, which stimulate chemotaxis and diapedesis of circulating leukocytes.
claimCytokines released by macrophages and dendritic cells (such as IL-1 and TNF-α) induce endothelial cells at the injury site to release Selectins and Integrins, which stimulate the chemotaxis and diapedesis of circulating leukocytes.
claimOnce circulating leukocytes enter a local injury site, they are activated by cytokines and chemokines secreted by macrophages and dendritic cells, subsequently releasing their own cytokines and mediators of inflammation.

claimThe term "interleukins" is derived from "inter," meaning between, and "leukocyte," which is another name for a white blood cell.
claimInterleukins are a type of cytokine named from 'inter' (between) and 'leukocyte' (white blood cell), though it is now known that cells other than leukocytes release them and they can relay messages between non-leukocyte cells.
claimImmune cells, also known as white blood cells or leukocytes, release most of the body's cytokines, though many other cell types also release them.
claimInterleukins are a type of cytokine that relays messages between cells, including cells that are not leukocytes.
Inflammation: Types, symptoms, causes, and treatment medicalnewstoday.com 2 facts
claimDuring acute inflammation, small blood vessels enlarge to enable leukocytes and plasma proteins to reach the site of an injury more easily.
procedureDuring acute inflammation, tissues accumulate plasma proteins, causing fluid buildup that results in swelling, and the body releases neutrophils (a type of white blood cell or leukocyte) that move toward the affected area to fight pathogens.

claimDuring the luteal phase, rising progesterone levels cause a decrease in acidophilic vaginal epithelial cells, which are replaced by an increasing number of leukocytes.

claimImmune responses are mediated by leukocytes, which derive from precursors in the bone marrow.
The Four Stages of Wound Healing woundevolution.com 1 fact
claimThe inflammation phase of wound healing is defined by vasodilation, where blood vessels dilate to allow enzymes and leukocytes (white blood cells) to enter the wound site to prevent infection.

claimIL-6 stimulates several types of leukocytes and the production of acute phase proteins in the liver, and it is important in inducing B-cells to differentiate into antibody-forming plasma cells.
The Center for Inflammation Science and Systems Medicine wertheim.scripps.ufl.edu 1 fact
claimDuring an acute inflammatory response, the immune system dispatches white blood cells, specifically leukocytes and macrophages, to migrate from the blood to the site of infection or injury to protect and surround the area.
