Summary
Trained immunity, a form of innate immune memory, may explain varied healing after root canal treatment. This immune priming influences periapical tissue repair and bone regeneration, offering a new perspective beyond infection control.
Area of Science:
- Immunology
- Endodontics
- Regenerative Medicine
Background:
- Periapical healing after root canal treatment shows significant variability despite consistent microbial control.
- Trained immunity, involving epigenetic and metabolic reprogramming of innate immune cells, offers a novel explanation for this variability.
- Previous inflammatory exposures may prime periapical tissues, altering healing responses.

Cell-mediated Immune Responses
Overview
Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
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...

Immunological Memory
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...

Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
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 create...
