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 ...

Due to the possibility of false positives, positive test results are usually reported as "reactive." This indicates that the assay reacted to antibodies, but this does not mean that the individual has the specific antibodies tested for. [5] Seroreversion is the opposite of seroconversion.
All IEL T cells are antigen-experienced T cells, which typically display a cytotoxic functional phenotype. IELs mediate antigen-specific delayed-type hypersensitivity (DTH) responses, exhibit virus-specific CTL function, to express natural killer (NK)-like activity and produce a local graft-versus-host reaction (GVHR) when transferred to ...
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]
B-lymphocyte antigen CD20 or CD20 is B lymphocyte cell-surface molecule. It is a 33-37 kDa non-glycosylated protein. CD20 is expressed on the surface of B-cells from the pre-B phase, the expression is lost in terminally differentiated plasma cells. [5] [6] CD20 is used as a therapeutical target of B-cell malignancies and autoimmune diseases. [6]
CD163 (Cluster of Differentiation 163) is a protein that in humans is encoded by the CD163 gene. [5] CD163 is the high affinity scavenger receptor for the hemoglobin-haptoglobin complex [6] and in the absence of haptoglobin - with lower affinity - for hemoglobin alone. [7]
Monoclonal B-cell lymphocytosis (MBL) is an asymptomatic condition in which individuals have increased blood levels of particular subtypes of monoclonal lymphocytes (i.e. an aberrant and potentially malignant group of lymphocytes produced by a single ancestral cell).
