Cells of the Innate Immune Response01:28

Cells of the Innate Immune Response

8.8K
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...

Introduction to Innate and Adaptive Immunity

9.1K
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,...

Lymphoid Cells and Tissues

3.0K
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

2.1K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

9.0K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Area of Science:

  • Immunology
  • Cell Biology

Background:

  • Innate lymphoid cells (ILCs) are key players in the innate immune system, acting as counterparts to T cells.
  • They are found in various organs, especially mucosal barriers, interfacing with environmental factors like microbes and allergens.

Purpose of the Study:

  • To review the current understanding of innate lymphoid cell functions.
  • To explore the role of ILCs in mucosal immunity concerning infections, allergies, and autoimmune disorders.

Main Methods:

  • Literature review of existing research on innate lymphoid cells.
  • Synthesis of data on ILC functions in gastrointestinal, respiratory, and oral mucosal immunity.

Main Results:

  • ILCs secrete effector cytokines and modulate other immune cells.
  • Their functions are critical in managing immune responses at mucosal surfaces.
  • ILCs play significant roles in host defense against pathogens and in allergic and autoimmune conditions.

Conclusions:

  • Innate lymphoid cells are vital for maintaining mucosal homeostasis and immunity.
  • Further research into ILCs can lead to novel therapeutic strategies for mucosal diseases.
