Endosymbiosis and cellular tolerance in the Hawaiian soft coral Sarcothelia edmondsoni verrill

Advances in Experimental Medicine and Biology
E H Mercer, A P Singh

Abstract

The relationship between the soft coral Sarcothelia edmondsoni Verrill and its symbiotic algae is considered as an early instance of cellular tolerance which can be disturbed by a variety of adverse conditions. The algal cells lie in vesicles deep within the endodermal cells of the host and are not subject to digestion. Their expulsion appears to be a reverse translocation to the distal end of the host cell and escape by a form of reversed phagocytosis resembling secretion. The cellular mechanisms involved are not clear.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
