Respiratory tract immune response to microbial pathogens.

B N Wilkie

    Journal of the American Veterinary Medical Association
    |November 15, 1982
    PubMed
    Summary

    Effective respiratory tract immunity relies on mucosal surfaces, involving antibody and cell-mediated responses. Vaccines are crucial for preventing respiratory diseases.

    Area of Science:

    • Immunology
    • Infectious Diseases
    • Vaccinology

    Background:

    • Respiratory tract infections are primarily resisted by specific immunity on mucosal surfaces.
    • Immune responses involve both antibody and cell-mediated systems, inducible by various antigen presentation methods.
    • The lungs possess more robust protective mechanisms than the trachea or nose.

    Purpose of the Study:

    • To review the mechanisms of respiratory tract immunity.
    • To discuss the induction and differences in immune competence between upper and lower respiratory tracts.
    • To highlight the role of vaccines in preventing respiratory diseases.

    Main Methods:

    • Literature review of immunological and vaccinology studies.
    • Analysis of respiratory tract immune system components and functions.
    • Examination of vaccine efficacy for respiratory tract infections.

    Main Results:

    • Specific mucosal immunity is key to resisting respiratory infections.
    • Both replicating agents and immunogenic antigens can induce immune responses.
    • Significant differences exist in the immunologic competence of the upper and lower respiratory tracts.

    Conclusions:

    • Understanding respiratory tract immunity is vital for disease prevention.
    • Vaccines represent a successful strategy for managing respiratory tract diseases.
    • Further research into mucosal immunology can lead to improved vaccines.
