Two More Members Of The Omicron Family To Keep An Eye On

Here we examine some of these emerging substrains and how they could impact viral characteristics like transmission, immune evasion, and virulence.

Quantitative Markers for Covid-19 Brain Injury

Recent studies investigating the blood and cerebrospinal fluid (CSF) of Covid-19 patients may provide an objective measure for the ongoing neurological symptoms that millions of people have experienced throughout the pandemic.

Coronaviruses Can Recombine With Cellular And Heterologous Viruses To Create Unexpected Variants

Here we examine the possibility of SARS-CoV-2 recombining with heterologous viruses, potentially leading to new variants.

The Artful Dodger SARS-CoV-2: Evading Immunity By Inhibition Of Interferon

A new study documents the SARS-CoV-2 variants’ evolution to become resistant to interferons and helps to explain how the virus may become more evasive to innate and adaptive immunity.

Hide And Seek: How Group 3 Innate Lymphoid Cells Help Cloak ACE2 Receptors From SARS-CoV-2

Covid-19 affects many organs throughout the body, including those of our gastrointestinal tract. Here, we describe how group 3 innate lymphoid cells (ILC3s) help protect our gut from SARS-CoV-2 infection.

Group 3 Innate Lymphoid Cells (ILC3s) And Trained Immunity: Faster And Stronger.

Covid-19 affects many organs throughout the body, including those of our gastrointestinal tract. This is part four of a series on the immune processes that protect our gut in the face of SARS-CoV-2 and other infections.

New And Effective Monoclonal Antibody Treatment For Ebola On The Horizon

A recently discovered set of monoclonal antibodies for ebolaviruses provides a key not only for untreated strains of ebola but also for many other viruses as well.

Innate Lymphoid Cells (ILCs): Guardians Against Infection

This is part three of a series on the immune processes that protect our gut in the face of SARS-CoV-2 and other infections. Here, we give an overview of innate lymphoid cells (ILCs), a recently discovered family of innate immune cells.

Imaging the Brain: What Brain Scans Reveal About the Consequences of Covid-19

A recent report from the Journal of Nuclear Medicine reviews the likely mechanisms underlying structural damage to the brain caused by Covid-19. Researchers are confident that for a majority of people these deficits will not be permanent or unresponsiv…

A Primary Defense Against SARS-CoV-2: Defensins

Recent research suggests that a family of proteins called defensins are a crucial tool in our body’s defense against SARS-CoV-2.
