Re: molecular mechanism of inflammation

... or other stimuli. (The stimulus may even be an eicosanoid from a neighboring cell; the pathways are complex.) This triggers the release of a phospholipase at the cell membrane. The phospholipase travels to the nuclear membrane. There, the phospholipase catalyzes ester hydrolysis of phospholipid ...

Re: lysosome

... "glycocalix" proteins but almost no references on a Pubmed search of lysosome + glycocalix. The lysosomes do indeed contain enzymes with phospholipase activity capable of damaging membranes, but these might not have access to the membranes without protein interactions. It seems that bits ...

cAMP as second messenger in GPCR signal transduction

... we have. other examples include cGMP and Calcium ions. And no, GPCRs do relay the message solely through cAMP, they can, as I remember, activate phospholipase C and guanynyl cyclase as well.

... same gland as the venom gland of the gila monster. The venom produced by a varanid lizard also shares many toxins with the gila monster, such as phospholipase A2 toxins that block the aggregation of platelets, an essential aspect of being able to form a blood clot to stop bleeding. This works ...
