Study explores lectins from plants, fungi, algae and cyanobacteria as pan-coronavirus inhibitors

In a recently published article scientists have provided a detailed description of the utility of mannose-specific lectins in preventing coronavirus infections. They have specifically explained how mannose-specific lectins derived from plants, algae, fungi, and bacteria selectively bind N-glycans present on the surface of viral spike protein and how such interactions can be medically utilized to control coronavirus transmission.

GLS1 inhibitor selectively eliminates senescent cells, ameliorates age-associated disorders

Senescent cells accumulate in organs during aging, promote tissue dysfunction, and cause numerous aging-related diseases like cancer. The cells arise through a process called "cellular senescence," a permanent cell cycle arrest resulting from multiple stresses.
