Experimental evidence is presented for drastic changes in phosphomonoesterase activities of tissue cultures, brought about by infection with poliomyelitis viruses. Acid phosphatase activity went through a maximum before decreasing almost to zero level. Alkaline phosphatase activity diminished
The regulation of cell surface receptor expression is essential for immune cell differentiation and function. At the plasma membrane ubiquitination is an important post-translational mechanism for regulating expression of a wide range of surface proteins. MARCH9, a member of the RING-CH family of
In the chronically denervated muscles of patients with prior paralytic poliomyelitis, there are secondary myopathic features, including endomysial inflammation and rare vacuolated fibers. To assess the frequency and characteristics of the vacuoles and their similarities with those seen in inclusion
Molecular mimicry is one of the mechanisms by which enterovirus infections have been postulated to have a role in the pathogenesis of type 1 diabetes. Immunogenic epitopes in enterovirus capsid protein VP1 and procapsid protein VP0 have sequence similarities with diabetes-associated epitopes in
Viruses use specific receptor molecules to bind selectively to target cells. Receptors have often been considered as mere docking sites, but they may also possess intrinsic signaling capacities that serve to prime the cell for entry and infection. Poliovirus (PV) initiates infection by binding to
