Alternatively, fatty acids can be converted to lipid intermediates like diacylglycerol, ceramides and fatty acyl-CoAs. These lipid intermediates can impair cellular function, which is referred to as lipotoxicity. [2] Adipocytes, the cells that normally function as lipid store of the body, are well equipped to handle the excess lipids. Yet, too ...
A major application of cellular adoptive therapy is cancer treatment, as the immune system plays a vital role in the development and growth of cancer. [1] The primary types of cellular adoptive immunotherapies are T cell therapies. Other therapies include CAR-T therapy, CAR-NK therapy, macrophage-based immunotherapy and dendritic cell therapy.
In TLS, the breakdown occurs after cytotoxic therapy or from cancers with high cell turnover and tumor proliferation rates. [4] The metabolic abnormalities seen in tumor lysis syndrome can ultimately result in serious complications such as acute uric acid nephropathy , acute kidney failure , seizures , cardiac arrhythmias , and death.
In non-adipocytes, lipid storage, lipid droplet synthesis and lipid droplet growth can be induced by various stimuli including growth factors, long-chain unsaturated fatty acids (including oleic acid and arachidonic acid), oxidative stress and inflammatory stimuli such bacterial lipopolysaccharides, various microbial pathogens, platelet ...
ITCLD-GT occurs more commonly in males of middle age (median age 48.4, range 15–77 years in one study). [2] Individuals with the disease present with GI tract symptoms which often are serious and/or debilitating [9] and may mimic those occurring in malignant lymphoproliferative, inflammatory, or autoimmune bowel diseases. [4]
Normally, these lipids are stored as lipid droplets and are normally used for metabolism, cell signaling and trafficking of vesicles. [2] Neutral lipid storage disease is a disease that is diagnosed with the simultaneous occurrence of myopathy and/or ichthyosis. Myopathy is defined as a disease of the muscle tissue.
In Adoptive T cell transfer therapy, TILs are expanded ex vivo from surgically resected tumors that have been cut into small fragments or from single cell suspensions isolated from the tumor fragments. Multiple individual cultures are established, grown separately and assayed for specific tumor recognition.
The actual T cell receptor is composed of two separate peptide chains, which are produced from the independent T cell receptor alpha and beta (TCRα and TCRβ) genes. The other proteins in the complex are the CD3 proteins: CD3εγ and CD3εδ heterodimers and, most important, a CD3ζ homodimer, which has a total of six ITAM motifs.
