  2. Immune response - Wikipedia

    en.wikipedia.org/wiki/Immune_response

    An immune response is a physiological reaction which occurs within an organism in the context of inflammation for the purpose of defending against exogenous factors. These include a wide variety of different toxins, viruses, intra- and extracellular bacteria, protozoa, helminths, and fungi which could cause serious problems to the health of the host organism if not cleared from the body.

  3. Viral strategies for immune response evasion - Wikipedia

    en.wikipedia.org/wiki/Viral_strategies_for...

    Hepatitis C Virus Life Cycle. The mammalian immune system has evolved complex methods for addressing and adapting to foreign antigens. At the same time, viruses have co-evolved evasion machinery to address the many ways that host organisms attempt to eradicate them.

  4. Immune system - Wikipedia

    en.wikipedia.org/wiki/Immune_system

    The adaptive immune system evolved in early vertebrates and allows for a stronger immune response as well as immunological memory, where each pathogen is "remembered" by a signature antigen. [55] The adaptive immune response is antigen-specific and requires the recognition of specific "non-self" antigens during a process called antigen ...

  5. Adaptive immune system - Wikipedia

    en.wikipedia.org/wiki/Adaptive_immune_system

    T cells contribute to immune defenses in two major ways: some direct and regulate immune responses; others directly attack infected or cancerous cells. [7] CD4+ lymphocytes, also called "helper" T cells, are immune response mediators, and play an important role in establishing and maximizing the capabilities of the acquired immune response. [3]

  6. Cross-presentation - Wikipedia

    en.wikipedia.org/wiki/Cross-presentation

    Consequently, immune responses against viruses that are able to do so, such as herpes viruses, are largely dependent on cross-presentation for a successful immune response. Overall, cross presentation aids in facilitating an adaptive immune response against intracellular viruses and tumor cells. [6]

    Alopecia areata is an immune response, meaning it’s caused by how your body defends itself against viruses, bacteria, and other foreign substances. Immune responses can be inflammatory, and some ...

  8. Viral pathogenesis - Wikipedia

    en.wikipedia.org/wiki/Viral_pathogenesis

    Viral disease is the sum of the effects of viral replication on the host and the host's subsequent immune response against the virus. [3] Viruses are able to initiate infection, disperse throughout the body, and replicate due to specific virulence factors. [2] There are several factors that affect pathogenesis.

  9. Neutralizing antibody - Wikipedia

    en.wikipedia.org/wiki/Neutralizing_antibody

    Mutations that allow viruses to evade a neutralizing antibody will be selected for, and hence prevail. Conversely, antibodies also simultaneously evolve by affinity maturation during the course of an immune response, thereby improving recognition of viral particles. Conserved parts of viral proteins that play a central role in viral function ...
