If the lymph node or similar tissue is reactive, or otherwise benign, it should possess a mixture of kappa positive and lambda positive cells. If, however, one type of light chain is significantly more common than the other, the cells are likely all derived from a small clonal population, which may indicate a malignant condition, such as B-cell ...
Cells in the mitotic phase are identified by the typical appearance of their chromosomes in the cell during the mitotic phase of the cell cycle. [4] Usually the number of mitotic figures is expressed as the total number in a defined number of high power fields, such as 10 mitoses in 10 high power fields.
There are approximately twice as many kappa-producing plasma cells as lambda plasma cells. Kappa free-light chains are normally monomeric, while lambda free-light chains tend to be dimeric, joined by disulphide bonds. Polymeric forms of both types of free light chain can also occur. [6]
CD19 is widely expressed during all phases of B cell development until terminal differentiation into plasma cells. During B cell lymphopoiesis, CD19 surface expression starts during immunoglobulin (Ig) gene rearrangement, which coincides during B lineage commitment from hematopoietic stem cell. [8]
All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood cells; Mean corpuscular hemoglobin concentration (MCHC)
Cancer can be seen as a disturbance in the homeostatic balance between cell growth and cell death. Over-expression of anti-apoptotic genes, and under-expression of pro-apoptotic genes, can result in the lack of cell death that is characteristic of cancer. An example can be seen in lymphomas. The over-expression of the anti-apoptotic Bcl-2 ...
A standard cocktail of antibodies can be designed to remove or purify mature hematopoietic cells or to detect Cluster of differentiation from a sample. Those antibodies are e.g. targeted to CD2 , CD3 , CD4 , CD5 , CD8 , NK1.1 , B220 , TER-119, and Gr-1 in mice and CD3 (T lymphocytes), CD14 (Monocytes), CD16 (NK cells, granulocytes), CD19 (B ...
Varlilumab is an IgG1 antibody that binds to CD27 and is an experimental cancer treatment. [6] This agonist antibody stimulates CD27 when it binds. [ 6 ] The drug is in early clinical trials and appears to stimulate T cells and increase production of cytokines such as interferon-gamma.
