Summary
Invariant natural killer T (iNKT) cells are crucial for resolving inflammation and promoting tissue repair. This process relies on interleukin-4 signaling to transition from inflammatory responses to healing.
Area of Science:
- Immunology
- Inflammation resolution
- Tissue homeostasis
Background:
- Resolution of inflammation is essential for tissue homeostasis.
- Mechanisms regulating the transition from inflammation to repair are not fully understood.
Purpose of the Study:
- To investigate the role of invariant natural killer T (iNKT) cells in inflammation resolution.
- To elucidate the molecular pathways involved in switching from inflammation to tissue repair.
Main Methods:
- Study utilized invariant natural killer T (iNKT) cell models.
- Investigated the role of interleukin-4 (IL-4) in the resolution process.
Main Results:
- Invariant natural killer T (iNKT) cells play a critical role in resolving inflammation.
- Interleukin-4 (IL-4) is a key mediator in this transition from inflammation to repair.
Conclusions:
- Invariant natural killer T (iNKT) cells are pivotal regulators of inflammation resolution.
- The findings highlight an IL-4-dependent mechanism for switching inflammation to tissue repair.

Liver Regeneration
4.5K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Tissue Renewal without Stem Cells
2.2K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.

Cells of the Innate Immune Response
9.7K
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...

Inflammatory Response
17.3K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Liver Histology
4.7K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
