Abstract:
Epstein-Barr virus (EBV) is a very successful human pathogen, with ~95% seroprevalence worldwide (Mentzer et al, Nat Commun 13:1818, 2022). If contracted in early childhood, EBV infection is typically asymptomatic; however, infections in adolescence and adulthood can manifest as infectious mononucleosis (IM). The innate immune response is the first line of defense, and its function is critical for controlling EBV infection. During EBV infection, components of the virus, known as pathogen-associated molecular patterns (PAMPs), are recognized by germline-encoded pattern recognition receptors (PRRs). PRRs are found on both non-immune and immune cells including antigen-presenting cells, such as macrophages, monocytes, dendritic cells, natural killer (NK), and mast cells. PRRs are also found on B cells and epithelial cells, the primary targets of EBV infection. Without immune surveillance, EBV can transform cells inducing various malignancies. Conversely, a prolonged innate immune response can lead to chronic inflammation which increases the likelihood of cancer. This review discusses innate immune recognition of EBV and its associated diseases.

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...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
01:21Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...
