In certain cancers (especially myelomonocytic leukemia) excessive production of lysozyme by cancer cells can lead to toxic levels of lysozyme in the blood. High lysozyme blood levels can lead to kidney failure and low blood potassium, conditions that may improve or resolve with treatment of the primary malignancy. [citation needed]
The human genome contains theta-defensin genes, but they have a premature stop codon, hampering their expression. An artificial human theta-defensin, [ 40 ] retrocyclin , was created by 'fixing' the pseudogene , and it was shown to be effective against HIV [ 41 ] and other viruses, including herpes simplex virus and influenza A .
Human neutrophil defensin-1, -3, and -4 are elevated in nasal aspirates from children with naturally occurring adenovirus infection. [10] In one small study, a significant increase in alpha-defensin levels was detected in T cell lysates of schizophrenia patients; in discordant twin pairs, unaffected twins also had an increase, although not as ...
Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, but also structurally unique since it is composed of two different gene products, PlyCA and PlyCB, with a ratio of eight PlyCB subunits for each PlyCA in its active conformation.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Azurophils may contain myeloperoxidase, phospholipase A2, acid hydrolases, elastase, defensins, neutral serine proteases, bactericidal permeability-increasing protein, [1] lysozyme, cathepsin G, proteinase 3, and proteoglycans. [citation needed] Azurophil granules are also known as "primary granules". [2]
The following outline is provided as an overview of and topical guide to immunology: . Immunology – study of all aspects of the immune system in all organisms. [1] It deals with the physiological functioning of the immune system in states of both health and disease; malfunctions of the immune system in immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency ...
The proteins work together to: trigger the recruitment of inflammatory cells "tag" pathogens for destruction by other cells by opsonizing, or coating, the surface of the pathogen; form holes in the plasma membrane of the pathogen, resulting in cytolysis of the pathogen cell, causing its death; rid the body of neutralised antigen-antibody complexes.
