None:
IFN-γ function during a type-2 helminth infection remains enigmatic. Westfall et al. found an unexpected role for IFN-γ in limiting tissue damage during intestinal infection by Heligmosomoides polygyrus bakeri (Hpb). IFN-γ produced by CD8+ T cells stimulates stromal cells directly to recruit neutrophils, where they prevent tissue damage caused by the worms.

Immune Response Against Viral Pathogens
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
