In the germinal center early stage antibody-secreting B cells undergo isotype switching and transition into a plasma cell. Antibody production by B cells can quickly neutralize a potential infection. Once the infection is neutralized, B cells can become memory B cells, which exist in small numbers...

recall that each circulating B cell expresses a different antibody at the cell surface. When an animal is immunized with a protein, different B cells recognize different epitopes, giving rise to multiple B

"ThroughYapl, alpha-catenin tells epidermal stem cells to either proliferate or not proliferate, depending on the needs of the tissue," Camargo said. Camargo's group is conducting screening tests to find small molecules that mimicYapl, to induce skin regeneration at the site of a wound, or ...
IL-2 is a T-cell growth factor, promoting antigen-activated CD8 T-cells, CD4 T-cells, and NK cells; it also acts as a stimulator of the immunosuppressive T-regulatory (Treg) cells [22, 23]. HDIL-2 has a short serum half-life and has several notable toxicities. Elevated endothelial ...
The result of nondisjunction is aneuploidy, which is when cells contain either an extra or missing chromosome. In contrast, euploidy is when a cell contains the normal chromosome complement. Nondisjunction may occur any time a cell divides, so it can happen during mitosis, meiosis I, or meiosis...
