[Type 2 innate lymphoid cells and chronic rhinosinusitis]
Summary
Type 2 innate lymphoid cells (ILC2) are newly discovered cells that drive type 2 inflammation. Their enrichment in nasal polyps suggests a key role in chronic rhinosinusitis (CRS) development.
Area of Science:
- Immunology
- Cell Biology
Background:
- Type 2 innate lymphoid cells (ILC2) are a recently identified immune cell population.
- ILC2s produce key type 2 cytokines (IL-5, IL-13) in response to specific signals (IL-33, IL-25, TSLP).
- These cytokines are crucial for initiating and sustaining type 2 inflammation in humans.
Purpose of the Study:
- To review the discovery and immunological properties of ILC2.
- To explore the role of ILC2 in the context of chronic rhinosinusitis (CRS).
Main Methods:
- Literature review focusing on ILC2 discovery, function, and association with CRS.
- Analysis of studies investigating ILC2 presence in nasal polyps.
Main Results:
- Nasal polyps from CRS patients exhibit a higher concentration of ILC2.
- This enrichment indicates a potential critical involvement of ILC2 in the pathogenesis of nasal polyps.
Conclusions:
- ILC2s are significant players in type 2 inflammatory responses.
- Further research into ILC2 function in CRS is warranted to understand their role in nasal polyp development.

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...

01:28Cells of the Innate Immune Response
9.3K
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...

5.0K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

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...

01:24T Cell Types and Functions
2.5K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...
