Tuesday, April 04, 2023 - 4:00 AM
Description
Aging is classically conceptualized as an ever-increasing trajectory of damage accumulation and loss of function, leading to increases in morbidity and mortality. However, recent in vitro studies have raised the possibility of age reversal. Here, we

Antiviral Activity of Cell Membrane-Bound Amphiphilic Polymers

Date
Tuesday, April 04, 2023 - 4:00 AM
Description
We demonstrate that cholesterol-modified polyethylene glycol has antiviral activity, exerted by anchoring to plasma membranes and sterically inhibiting viruses from entering cells. These polymers distribute sparsely on cell membranes even at binding

Tissue-resident memory T cells and lung immunopathology

Date
Tuesday, April 04, 2023 - 4:00 AM
Description
Rapid reaction to microbes invading mucosal tissues is key to protect the host against disease. Respiratory tissue-resident memory T (T(RM) ) cells provide superior immunity against pathogen infection and/or re-infection, due to their presence at the
