"Our results indicate, however, that energy and nutrients from host microbes may pass through viruses into graz-ers and move up the food chain through virovory..."

Viruses impact host cells and have indirect effects on ecosystem processes. Plankton such as ciliates can reduce the abundance of virions in water,...

"In studies published in 2020 and 2021, Foxman and her colleagues reported that an initial infection of rhinovirus induced a strong and rapid innate immune response that prevented a subsequent infection with influenza or SARS-CoV-2 in an organoid model."

The “tripledemic” shines a spotlight on viral interference, in which one infection can block another.

Te invitamos a que leas este artículo sobre la exorribonucleasa (ExoN), una enzima rara codificada en algunos genomas de virus de RNA como el de los coronavirus.

Esta enzima quita ribonucleótidos (componentes del genoma de
RNA viral) que han sido erróneamente incorporados reduciendo la tasa de mutación del virus. Al no haber muchas mutaciones gracias a la ExoN, los coronavirus, como el , tienen uno de los genomas más grandes de todos los virus de RNA. Nosotros encontramos que muy probablemente la ExoN tiene un origen celular.

The findings, published today in Science, show that the virus's genetic code can be read in two different ways by cells the virus has infected. The result is that infected cells make two different forms of the virus's RNA.

New research on the structure of the human immunodeficiency virus (HIV) has revealed a promising novel drug target for treating HIV infection, which affects more than 1 million Americans and 40 million people worldwide. The findings, published today in Science, show that the virus's genetic code can...

The gold salt auranofin may be a promising addition to antiretroviral therapy (ART) to target individuals categorized as latent viral reservoirs of HIV-1.

Researchers have cleared a major obstacle in the development of an HIV vaccine, proving in animal models that effective, yet short-lasting antibodies can be coaxed into multiplying as a fighting force against the virus.

"In this work, the researchers also obtained samples of DENV2 from infected patients. They found that unlike the dengue viruses used in the laboratory, those from patients remained smooth at 37 degrees Celsius. At a fever temperature of 40 degrees, however, the bumpy surface emerged".

Four related types of dengue virus are common in at least 100 countries and threaten around three billion people. | Microbiology
