Proton and cation transport activity of the M2 proton channel from influenza A virus.

The M2 protein is a small, single-span transmembrane (TM) protein from the influenza A virus. This virus enters cells via endosomes; as the endosomes mature and become more acidic M2 facilitates proton transport into the viral interior, thereby disrupting matrix protein/RNA interactions required for infectivity. A mystery has been how protons can accumulate in the viral interior without develop...

Swine influenza matrix 2 (M2) protein contributes to protection against infection with different H1 swine influenza virus (SIV) isolates.

A swine influenza virus (SIV) vaccine-challenge pig model was used to study the potential of a conserved matrix 2 (M2) protein vaccine alone or in combination with an inactivated H1N1-vaccine to protect against H1N1 and H1N2 viruses. The H1N1-vaccine and heterologous H1N2-challenge virus model has previously been shown to prolong fever and increase SIV-associated pneumonic lesions. The M2 vacci...

Influenza A Virus M2 Ion Channel Protein:

A structure-function analysis of the influenza A virus M2 ion channel protein was performed. The M2 protein of human influenza virus A/Udorn/72 and mutants containing changes on one face of the putative a helix of the M2 transmembrane (TM) domain, several of which lead to amantadine resistance when found in virus, were expressed in oocytes of Xenopus laevis. The membrane currents of oocytes exp...

Influenza matrix protein 2 alters CFTR expression and function through its ion channel activity.

The human cystic fibrosis transmembrane conductance regulator (CFTR) is a cyclic AMP-activated chloride (Cl(-)) channel in the lung epithelium that helps regulate the thickness and composition of the lung epithelial lining fluid. We investigated whether influenza M2 protein, a pH-activated proton (H(+)) channel that traffics to the plasma membrane of infected cells, altered CFTR expression and ...

Sustained Autophagy Contributes to Measles Virus Infectivity

The interplay between autophagy and intracellular pathogens is intricate as autophagy is an essential cellular response to fight against infections, whereas numerous microbes have developed strategies to escape this process or even exploit it to their own benefit. The fine tuned timing and/or selective molecular pathways involved in the induction of autophagy upon infections could be the corner...
