Need to find references - the papers cited dont clearly talk about the toxin modulating cell migration under physiological conditions:
this term is not precise enough to know what process is being disrupted: epithelial cell migration /wound healing? macrophage migration / immune response
@genegodbold @pmasson55 @mgiglio99 @dsiegele
Do you have examples of modulation of host cell migration for bacteria/viruses?
@pgaudet What counts as modulation of migration? Lots of bacterial virulence factors paralyze phagocytes like macrophages by messing with their cytoskeleton. This usually abolishes the ability to move/migrate.
Other factors affect the chemokine environment so that they don't move as they would in the absence of those virulence factors. There are secreted Streptococcal proteases that cleave interleukin-8 and complement inflammatory mediators like C5a so that the host neutrophils "lose" coordination of the response with deleterious effects on the host.
Is this modulation of migration? I count the former as anti-phagocytic and use terms like PATHGO:0000232 (suppresses phagocytosis in another organism) OR PATHGO:0000231 (suppresses opsonization in another organism)
I also use PathGO terms specifying what aspect of the host cell cytoskeleton is disabled 'in another organism' PATHGO:0000028 (modulates cytoskeleton dynamics in another organism)
Nice! These are much more specific. Thanks for pointing this out.
Hi @pgaudet I reviewed all references linked to "cell migration" in UP entries of venoms, and found nothing physiological. Most of proteins were tested to find anti-cancer drugs. I suggest to definitely suppress the term "envenomation resulting ... cell migration in another organism".
