The innate immune system identifies microbes via pattern recognition receptors. This review explores if these, along with
Area of Science:
- Immunology
- Transplantation Biology
Background:
- The innate immune system is the primary defense against pathogens.
- It recognizes microbial non-self using specific molecular mechanisms.
- Recognition of non-microbial non-self, like organ transplants, is less understood.
Purpose of the Study:
- To review innate immune recognition mechanisms.
- To explore their applicability to allograft rejection.
- To understand 'damaged' self recognition.
Main Methods:
- Review of pattern recognition receptors (PRRs).
- Analysis of the 'missing self' theory.
- Examination of the 'danger' hypothesis.
Main Results:
- PRRs are key to microbial recognition.
- 'Missing self' and 'danger' hypotheses offer frameworks for non-self recognition.
- These mechanisms may play a role in allograft rejection.
Conclusions:
- Innate immune recognition mechanisms are complex.
- Understanding 'damaged' self recognition is crucial for transplantation.
- Further research is needed to clarify the role of innate immunity in allograft rejection.

What is the Immune System?
Introduction 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,...

Phagocytes
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...

Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
