Summary
Innate immunity uses pathogen-associated molecular patterns (PAMPs) and pattern-recognition receptors (PRRs) to detect and fight infections. This review details the molecular basis of PRRs like Toll-like and NOD receptors in immune cell activation.
Area of Science:
- Immunology
- Microbiology
- Molecular Biology
Context:
- Innate immunity serves as the primary defense against infectious agents.
- Understanding innate immune mechanisms is crucial for combating pathogens.
Purpose:
- To review the functioning of innate immunity.
- To discuss pathogen-associated molecular patterns (PAMPs) and pattern-recognition receptors (PRRs).
Summary:
- This review details the molecular and genetic structures of Toll-like receptors (TLRs) and NOD-receptors (NODRs), key PRRs.

Introduction to Innate and Adaptive Immunity
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: 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,...

Overview
Introduction to Lymphatic and Immune System
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.

Cells of the Innate Immune Response
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
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...

Acute Inflammation I: Inflammatory Response
Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Defense Mechanism Against Infection
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
