Abstract:
Candida albicans is a polymorphic fungus which is the predominant cause of superficial and deep tissue fungal infections. This microorganism has developed efficient strategies to invade the host and evade host defense systems. However, the host immune system will be prepared for defense against the microbe by recognition of receptors, activation of signal transduction pathways and cooperation of immune cells. As a consequence, C. albicans could either be eliminated by immune cells rapidly or disseminate hematogenously, leading to life-threatening systemic infections. The interplay between Candida albicans and the host is complex, requiring recognition of the invaded pathogens, activation of intricate pathways and collaboration of various immune cells. In this review, we will focus on the effects of innate immunity that emphasize the first line protection of host defense against invaded C. albicans including the basis of receptor-mediated recognition and the mechanisms of cell-mediated immunity.
Insights
Candida albicans infections are a major health concern. This review explores how innate immunity, through receptor recognition and cell-mediated responses, defends the host against this opportunistic fungus.
Area of Science:
- Immunology
- Mycology
Background:
- Candida albicans is a common fungus causing infections.
- It has mechanisms to invade hosts and evade immune defenses.
- Host immune responses are crucial for controlling C. albicans.
Purpose of the Study:
- To review the role of innate immunity in host defense against Candida albicans.
- To highlight receptor-mediated recognition and cell-mediated immunity.
Main Methods:
- Literature review focusing on innate immune mechanisms.

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,...
