What are Cytokines? Types & Function - Cleveland Clinic my.clevelandclinic.org Jan 3, 2023 10 facts
claimThe term "interleukins" is derived from "inter," meaning between, and "leukocyte," which is another name for a white blood cell.
claimLymphokines are a type of cytokine produced by lymphocytes, which are a type of 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.
claimCytokines signal cell differentiation by instructing immature cells to develop into specific cell types, such as instructing an immature cell to mature into a white blood cell capable of fighting infection.
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.
claimCytokines signal cell proliferation by instructing a cell to replicate itself, such as telling a white blood cell to produce more white blood cells to fight infection.
claimHematopoietic stem cells are precursor cells that give rise to all blood cell types, including white blood cells, red blood cells, and platelets, through a process called hematopoiesis.
claimHematopoiesis is the process where hematopoietic stem cells (HSC) develop into all blood cell types, including white blood cells, red blood cells, and platelets.
claimMonokines are a type of cytokine produced by monocytes, which are a type of white blood cell.
claimGranulocyte-colony stimulating factor (G-CSF) signals a hematopoietic stem cell to become a neutrophil, which is a type of white blood cell that helps fight infection.

procedureThe process of inflammation involves white blood cells releasing chemicals into the blood or tissues, which increases blood flow to the site of injury or infection, potentially causing redness and warmth.
claimInflammation is a biological process where the body's white blood cells and the substances they produce protect the body from injury or infection caused by outside invaders like bacteria and viruses.
claimIn joints, an accumulation of white blood cells and their associated substances can cause irritation, swelling of the joint lining, and the long-term loss of cartilage.
claimInflammation is the body's response to an injury, illness, or the perception of one, involving the activation of white blood cells to combat the problem.
The immune system and primary immunodeficiency primaryimmune.org 4 facts
claimThe most common cells of the immune system are lymphocytes (T cells, B cells, and NK cells), neutrophils, and monocytes/macrophages, all of which are types of white blood cells.
measurementNeutrophils, also known as polymorphonuclear leukocytes (polys or PMNs) or granulocytes, constitute about half or more of all white blood cells.
measurementMonocytes are white blood cells that circulate in the bloodstream and make up 5 to 10% of the total white blood cell count.
measurementMonocytes make up 5 to 10% of white blood cells.

claimAll cellular elements of blood, including red blood cells, platelets, and white blood cells, derive from hematopoietic stem cells located in the bone marrow.
claimAll cellular elements of blood, including red blood cells, platelets, and white blood cells, derive from hematopoietic stem cells located in the bone marrow.
claimWhite blood cells of the immune system derive from precursors in the bone marrow.

claimThe presence of clear fluid in or around a wound during the inflammation stage indicates that white blood cells are actively cleaning and defending the area.
claimMacrophages are white blood cells that arrive at a wound site during the inflammation stage to fight infection and release growth factors that aid in tissue repair.

measurementIn a study of 11 men on a low-copper diet (0.66 mg copper/day for 24 days and 0.38 mg/day for 40 days), white blood cells called mononuclear cells showed a reduced proliferation response when presented with an immune challenge in cell culture.
claimIn a study of 11 malnourished infants with copper deficiency, the ability of white blood cells to engulf pathogens increased significantly after one month of copper supplementation.

claimAcute inflammation manifests physically through symptoms such as swelling, redness, and pain as the body dispatches white blood cells to an injury site.
claimAcute inflammation is the body's immediate response to injury or infection, characterized by the immune system sending white blood cells to destroy damaging substances, heal tissues, and return the area to balance.

Inflammation: Types, symptoms, causes, and treatment medicalnewstoday.com 1 fact
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.
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.
