====== CD147 ====== The CD147 [[protein]] is a ubiquitous multifunctional [[membrane receptor]]. Expression of CD147, which is regulated by sterol carrier protein, reportedly modulates [[amyloid beta]] (Aβ), the neurotoxic [[peptide]] implicated in neuronal degeneration in [[Alzheimer disease]] (AD). ---- In [[glioma]], [[temozolomide resistance]] is due to overexpression of CD147 protein and induction of [[Nuclear factor-erythroid 2 related factor 2]] ((Luo GQ, Bai S, Hu Y, Chen H, Yan ZJ, Fan LL. CD147 Protein Expression and Temozolomide Resistance in Glioma Cells: An Ex vivo and In vivo Study. Cell Mol Biol (Noisy-le-grand). 2022 Jul 31;68(7):160-164. doi: 10.14715/cmb/2022.68.7.26. PMID: 36495502.)) ---- Findings reveal potentially important relationships between [[cholesterol]] loading, CD147 expression, Aβ toxicity, and the putative involvement of CYPA protein in neuroprotection in AD ((Kanyenda LJ, Verdile G, Martins R, Meloni BP, Chieng J, Mastaglia F, Laws SM, Anderton RS, Boulos S.
