Taken that (a) Gal-3 promotes RAB10-dependent macropinocytosis in GBM stem cells (discussed above) and (b) macrophages produce Gal-3 under inflammatory conditions, it is highly likely, but needs verification, that Gal-3 promotes RAB10-dependent macropinocytosis in macrophages too. Here, LGALS3 is linked to glioblastoma.
