Macropinocytosis is a clathrin-independent endocytic mechanism that can be activated in practically all animal cells, resulting in uptake. In most cell types, it does not occur continuously but rather is induced for a limited time in response to cell-surface receptor activation by specific cargoes, including growth factors , ligands of ...
Here, both infectious forms of VACV, mature virion (MV) and enveloped virion (EV), induce their own macropinocytosis by binding to the cell surface and triggering an actin-mediated plasma membrane protrusion that eventually collapses back onto the plasma membrane sealing the attached virion inside a macropinosome, which then goes through a ...

Also, blocking the macropinocytosis pathway has been proven to stop Ebolavirus from entering the cells. Four different macropinocytosis specific inhibitors were tested: cytochalasin D (depolymerizing agent), wortmannin (Wort), LY-294002 (both are inhibitors of PI3K) and EIPA (5-(N-ethyl-N-isopropyl) amiloride), an inhibitor of the Na+/H+ ...
MG132 is a potent, reversible, and cell-permeable proteasome inhibitor [1] (K i = 4 nM). It belongs to the class of synthetic peptide aldehydes. [2] [3] It reduces the degradation of ubiquitin-conjugated proteins in mammalian cells and permeable strains of yeast by the 26S complex without affecting its ATPase or isopeptidase activities.
Cell-penetrating peptides (CPP) are able to transport different types of cargo molecules across plasma membrane; thus, they act as molecular delivery vehicles. They have numerous applications in medicine as drug delivery agents in the treatment of different diseases including cancer and virus inhibitors, as well as contrast agents for cell ...
Some virulent bacteria produce proteins that either disrupt host cell membranes or stimulate their own endocytosis or macropinocytosis into host cells. These virulence factors allow the bacteria to enter host cells and facilitate entry into the body across epithelial tissue layers at the body surface. [citation needed] Immune response inhibitors
As of January 2019, three PI3K inhibitors are approved by the FDA for routine clinical use in humans: the PIK3CD inhibitor idelalisib (July 2014, NDA 206545), the dual PIK3CA and PIK3CD inhibitor copanlisib (September 2017, NDA 209936), and the dual PIK3CD and PIK3CG inhibitor duvelisib (September 2018, NDA 211155). Co-targeted inhibition of ...
