Abstract:
In this review, we demonstrate that wild-derived mouse strains (wild-DMS) represent a useful tool for dissecting the immune system. We confirm and extend the notion that we and others have previously advanced, which is that common laboratory mice are not fully representative of the whole genus Mus. We illustrate how wild-DMS helped us to unveil a novel B-cell population that, in contrast to the B-1 cell population, is present in the entire genus Mus, including common laboratory mice. Moreover, we suggest that Bw cells belong to the "natural memory" B-cell population that comprises B-1 and MZ B cells.
Insights
Wild-derived mouse strains reveal a novel B-cell population across the Mus genus. These findings enhance our understanding of the immune system and B-cell diversity in mice.
Area of Science:
- Immunology
- Genetics
- Mouse Models
Background:
- Common laboratory mice may not fully represent the diversity within the genus Mus.
- Understanding immune system variations requires diverse genetic backgrounds.
Purpose of the Study:
- To demonstrate the utility of wild-derived mouse strains (wild-DMS) for immune system research.
- To identify and characterize novel immune cell populations using wild-DMS.
Main Methods:
- Comparative analysis of immune cell populations in wild-derived and laboratory mouse strains.
- Characterization of newly identified B-cell populations.
Main Results:
- Wild-DMS are valuable tools for dissecting the immune system.
- A novel B-cell population, termed Bw cells, was identified across the genus Mus.
- Bw cells appear to be part of the natural memory B-cell population.
Conclusions:
- Wild-DMS provide unique insights into immune system diversity.
- The discovery of Bw cells expands the known repertoire of B-cell populations.
- Further research into Bw cells could elucidate their role in natural immunity.

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...

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...
01:15Secondary Lymphoid Organs
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...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
