They kill half a million people worldwide every year. These viruses can also wreak havoc on animals, as in the case of avian flu. A team has now identified how the influenza A virus manages to penetrate cells to infect them. By attaching itself to a receptor on the cell surface, it hijacks the iron transport mechanism to start its infection cycle. By blocking the receptor involved, the researchers were also able to significantly reduce its ability to invade cells. These results highlight a vulnerability that could be exploited to combat the virus.

Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.

In essence, the baseline immune statuses in men previously infected with SARS-CoV-2 was altered in ways that changed the response to an exposure different from SARS-CoV-2, the researchers report.

This scenario is particularly relevant in adult and elderly populations, where individuals have been exposed to flu viruses multiple times in the past and have low levels of M2e-specific antibodies in their blood circulation.
