Summary
Coronin 1 is not essential for natural killer (NK) cell number or function in mice. Studies show coronin 1-deficient NK cells exhibit normal homeostasis, activation, and cytotoxic activity.
Area of Science:
- Immunology
- Cell Biology
Background:
- Coronin 1, a WD repeat protein, is found in leukocytes, but its role in natural killer (NK) cell function is unknown.
- Understanding coronin 1's impact on NK cells is crucial for immune system research.
Purpose of the Study:
- To investigate the role of coronin 1 in the homeostasis and function of NK cells.
- To analyze NK cell numbers, phenotypes, and functional responses in coronin 1-deficient mice.
Main Methods:
- Analysis of NK cell counts and phenotypes in blood, spleen, and liver of coronin 1-deficient and wild-type mice.
- In vitro functional assays including interferon-γ production, degranulation, and calcium mobilization upon NK cell receptor stimulation.
- Assessment of NK cell cytotoxic activity and in vivo responses to Vesicular Stomatitis Virus (VSV) infection.
Main Results:
- Coronin 1-deficient mice had comparable absolute NK cell numbers and phenotypes to wild-type mice.
- NK cells from coronin 1-deficient mice showed normal functionality in response to activating receptors (NK1.1, NKp46, Ly49D, NKG2D).
- Cytotoxic activity and NK cell responses to VSV infection were similar in both groups.
Conclusions:
- Coronin 1 is dispensable for maintaining NK cell homeostasis and function in mice.
- These findings suggest coronin 1 does not play a critical role in NK cell biology.

9.3K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

7.8K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

01:17The Extrinsic Apoptotic Pathway
9.2K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.

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...
