Lymphotoxin beta is a type II membrane protein of the TNF family.It anchors lymphotoxin-alpha to the cell surface through heterotrimer formation. The predominant form on the lymphocyte surface is the lymphotoxin-alpha 1/beta 2 complex (e.g. 1 molecule alpha/2 molecules beta) and this complex is the primary ligand for the lymphotoxin-beta receptor.
Lauryl tryptose broth (LTB) is a selective growth medium for coliforms. [1] Lauryl tryptose broth is used for the most probable number test of coliforms in waters, effluent or sewage. It acts as a confirmation test for lactose fermentation with gas production. Sodium lauryl sulfate inhibits organisms other than coliforms.

LTB 4 is a leukotriene involved in inflammation. It is produced from leukocytes in response to inflammatory mediators and is able to induce the adhesion and activation of leukocytes on the endothelium , allowing them to bind to and cross it into the tissue. [ 1 ]
LTB 4 LTC 4 is a cysteinyl leukotriene, as are D4 and E4. LTD 4 LTE 4 Leukotrienes are a family of eicosanoid inflammatory mediators produced in leukocytes by the oxidation of arachidonic acid (AA) and the essential fatty acid eicosapentaenoic acid (EPA) by the enzyme arachidonate 5-lipoxygenase .
[1] [2] [3] The resulting 5-HPETE yields the unstable allylic epoxide substrate LTA 4 [4] which is quickly hydrolyzed by the leukotriene A4 hydrolase (LTA 4 H) enzyme to produce LTB 4, or synthesized by leukotriene C4 synthase (LTC 4 S) with the addition of glutathione to produce LTC 4 which can be further metabolized to produce leukotriene D 4 ...
Latent tuberculosis (LTB), also called latent tuberculosis infection (LTBI) is when a person is infected with Mycobacterium tuberculosis, but does not have active tuberculosis (TB). Active tuberculosis can be contagious while latent tuberculosis is not, and it is therefore not possible to get TB from someone with latent tuberculosis.
Leukotriene-A4 hydrolase is an enzyme that catalyzes the reaction which converts Leukotriene A4 to Leukotriene B4. [1] It is a bifunctional zinc enzyme (EC 3.3.2.6) with different amino acids attached to it to aid in the catalysis of the reaction.
