claimCytokines secreted by immune cells during the early stages of inflammation stimulate the liver to synthesize acute-phase proteins.
claimLipids are metabolized by immune cells to generate energy and serve as structural and functional components of cell membranes.
claimVitamin A deficiency affects functional activities of immune cells, including chemotaxis, phagocytosis, and the ability to generate oxidants that kill invading pathogens.
claimMonocytes, macrophages, and neutrophils are key immune cells that engulf and digest invading microorganisms through a process known as phagocytosis.
claimLeptin promotes the phagocytic function of immune cells, stimulates pro-inflammatory cytokine production, and regulates the functions of neutrophils, natural killer (NK) cells, and dendritic cells.
claimExposure to a specific antigen on an invading pathogen stimulates the production of immune cells that target that pathogen for destruction.
claimThe vitamin D receptor (VDR) is expressed in several types of immune cells, including monocytes, macrophages, dendritic cells, and activated T cells.
claimLong-chain polyunsaturated fatty acids (PUFAs) are incorporated into the membrane phospholipids of immune cells, where they modulate cell signaling processes such as phagocytosis and T-cell signaling.
claimVitamin C is an antioxidant that protects cells against reactive oxygen species generated by immune cells to kill pathogens.
What are Cytokines? Types & Function - Cleveland Clinic my.clevelandclinic.org Jan 3, 2023 8 facts
claimTumor necrosis factor (TNF) is a cytokine that helps regulate inflammation and signals immune cells to kill tumor cells.
claimCytokines signal cell activation by directing immune cells toward infection sites to fight germs and by heightening or lessening processes associated with inflammation.
claimIn autoimmune diseases, the body's immune cells mistakenly attack healthy 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.
claimImmune cells that release cytokines include macrophages, dendritic cells, lymphocytes (T and B lymphocytes), monocytes, neutrophils, basophils, eosinophils, and mast cells.
claimChemokines are a type of cytokine that direct immune cells toward locations in the body where they can fight infection.
claimCytokines function as chemical messengers that signal immune cells to fight invading pathogens such as viruses and bacteria.
claimInflammation serves as a sign that the body's immune cells are fighting invaders or healing tissue damage.
Parts of the Immune System | Children's Hospital of Philadelphia chop.edu 6 facts
claimWhen a pathogen is detected, nearby lymph nodes (draining lymph nodes) undergo cell activation, chemical signaling, and expansion of immune cell numbers, which can cause the nodes to increase in size and become tender.
claimLymph nodes are tissues filled with immune cells that are located throughout the body.
claimHelper T cells oversee cytokine signaling to activate B cells and increase the efficiency of other immune cells, such as macrophages.
claimThe secretion of cytokines by macrophages recruits other immune cells to the area, which leads to inflammation.
claimLymph nodes are tissues filled with immune cells that are located throughout the body, with higher prevalence near body openings like the digestive tract and genital region.
claimMost immune cells activated during an infection die during or shortly after the infection.
Pro-Inflammatory Cytokines Overview | Thermo Fisher Scientific - US thermofisher.com 5 facts
claimPro-inflammatory cytokines regulate growth, cell activation, differentiation, and the homing of immune cells to sites of infection to control and eradicate intracellular pathogens like viruses.
claimIn the context of viral lung infections, resident macrophages phagocytose apoptotic cells and subsequently release pro-inflammatory cytokines, which recruit other immune cells, cause acute inflammation, and provoke fever and fibrosis.
claimCytokines are small secreted proteins that act as key modulators of inflammation and are produced in response to invading pathogens to stimulate, recruit, and proliferate immune cells.
claimCXC chemokines are primarily involved in recruiting immune cells to sites of inflammation and mediating homeostatic migration and homing of lymphocytes.
claimImmune cells communicate via cytokines, which control cell proliferation, differentiation, and function, and are involved in inflammation, hematopoiesis, neurogenesis, embryogenesis, and oncogenesis.

measurementThe pathobiology of acute respiratory distress syndrome (ARDS) is characterized by massive infiltration of immune cells into the lung, sustained vascular permeability, lung flooding, severe hypoxemia, and a 40% mortality rate.
claimThe protective process of inflammation helps accommodate the influx of immune cells, reduces further tissue damage by limiting excessive usage, and prevents the threat from spreading throughout the body.

Infection vs Inflammation: What Your Wound Is Telling You altitudedermatology.com Jul 15, 2025 1 fact
claimDuring the inflammatory process, immune cells release inflammatory mediators such as bradykinin and histamine, which dilate small blood vessels near the wound to increase the flow of oxygen-rich blood to the area for tissue repair.
