A killer yeast is a yeast, such as Saccharomyces cerevisiae, which is able to secrete one of a number of toxic proteins which are lethal to susceptible cells. [1] These "killer toxins" are polypeptides that kill sensitive cells of the same or related species, often functioning by creating pores in target cell membranes.
The virus must go through a sequence of steps to do this, beginning with binding to a specific "receptor" molecule on the surface of the host cell and ending with the virus "uncoating" inside the cell and releasing its contents. Viruses that have a lipid envelope must also fuse their envelope with the target cell, or with a vesicle that ...
Aristolochic acid (contained in herbs in the genus Aristolochia e.g. Aristolochia serpentaria (Virginia snakeroot), Aristolochia reticulata (Texas snakeroot) and in Chinese herbs such as Aristolochia fangchi and Aristolochia manshuriensis [7] (banned in China and withdrawn from Chinese Pharmacopoea 2005; Stephania tetrandra and Magnolia ...

How else to protect yourself from viruses this winter. Respiratory viruses are the biggest reasons people get sick in winter, Dr. Russo says. “You can get infected through fomites [infected ...
When host cells die, either by apoptosis or by cell injury due to an infection, phagocytic cells are responsible for their removal from the affected site. [9] By helping to remove dead cells preceding growth and development of new healthy cells, phagocytosis is an important part of the healing process following tissue injury.
