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 ...
Bcl-2 derives its name from B-cell lymphoma 2, as it is the second member of a range of proteins initially described in chromosomal translocations involving chromosomes 14 and 18 in follicular lymphomas. Orthologs [9] (such as Bcl2 in mice) have been identified in numerous mammals for which complete genome data are available.
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]
Lambda strains, mutated at specific sites, are unable to lysogenize cells; instead, they grow and enter the lytic cycle after superinfecting an already lysogenized cell. [ 3 ] The phage particle consists of a head (also known as a capsid ), [ 4 ] a tail, and tail fibers (see image of virus below).
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]
CD2 is a specific marker for T cells and NK cells, and can therefore be used in immunohistochemistry to identify the presence of such cells in tissue sections. The great majority of T cell lymphomas and leukaemias also express CD2, making it possible to use the presence of the antigen to distinguish these conditions from B cell neoplasms.
Because the receptors for type I and type II interferons are expressed on almost all nucleated cells, their function is rather systemic. Type III interferon receptors are expressed more specifically on epithelial cells and some immune cells such as neutrophils , and depending on the species, B cells and dendritic cells as well.
Type 2 inflammation is a pattern of immune response. Its physiological function is to defend the body against helminths , but a dysregulation of the type 2 inflammatory response has been implicated in the pathophysiology of several diseases.
