Scientists uncover HIV’s sweet spot

HIV researchers have long been trying to identify the specific cells that the virus prefers to infect and hide in. They know that HIV favors a special type of immune cells called memory CD4 T cells.

How Pfizer won the pandemic, reaping outsize profit and influence

The grinding two-plus years of the pandemic have yielded outsize benefits for one company — Pfizer — making it both highly influential and hugely profitable as covid-19 continues to infect tens of thousands of people and kill hundreds each day.

Scientists discover how a protein and enzymes interact to allow hepatitis A virus replication

The viral replication cycle is crucial for a virus to spread inside the body and cause disease. Focusing on that cycle in the hepatitis A virus (HAV), UNC School of Medicine scientists discovered that replication requires specific interactions between the human protein ZCCHC14 and a group of enzymes called TENT4 poly(A) polymerases.

Age-specific precision shielding in the pre-vaccination period of the COVID-19 pandemic

A new study has focussed on addressing whether age-specific precision shielding was achieved in the pre-vaccination period.

Most therapeutic antibodies for treating COVID-19 patients do not inhibit emerging Omicron subvariants

The Omicron subvariants BA.1 and BA.2 of SARS-CoV-2 have dominated the COVID-19 pandemic in early 2022. In many countries, these viruses are now outcompeted by emerging subvariants, with BA.5 being responsible for the current uptick of cases in Germany.
