Each antibody-producing B cell makes antibodies of unique specificity, reflecting a series of ordered gene rearrangements which must be successfully performed if the cell is to survive. A second selection process occurs during immune responses in which a new antibody repertoire is generated through som...

B cells are a type of lymphocytes that play an important role in the adaptive immune system. These cells express B-cell receptors (BCR) comprising two identical heavy chains (HC) and two identical light chains (LC) that allow the B cell to bind to an antigen. An individual’s repertoire ...
Large subclonal expansions were associated with positive subclonal selection. Patients with tumours harbouring recent subclonal expansions, on the terminus of a phylogenetic branch, had significantly shorter disease-free survival. Subclonal WGD was detected in 19% of tumours, and 10% of tumours ...

Mutations in these five genes accounted for 77% of identified CHIP mutations in aplastic anemia, and the underrepresentation of TET2, JAK2, and TP53 suggests a different mechanism of clonal selection occurs in an aplastic bone marrow microenvironment. Serial sampling revealed that BCOR, BCORL1, and...
Chromosomes, the shapes and locations on those chromosomes that contain our genes are located in specific cell types, including sperm and egg cells that are released into the world.Answer and Explanation: Clonal selection is a process by which one or more individuals are selected as a form of ...

When cloning trees of various ages, it is important to determine first which part of the individual contains the most responsive cells and at what time of the year these cells are in the most responsive state. This allows selection of the most useful explants. In hardwood trees and a few ...
White blood cells (WBCs) were labeled with anti-CD3 (for selection of T cells) and anti-CD33 (for selection of myeloid cells) monoclonal antibodies (Beckton-Dickinson, Heidelberg, Germany) or isotypic controls, respectively. Between 5 × 104 and 105 CD3+ and CD33+ cells were sorted on a...
