Molecular Mechanisms of Virus Assembly and Entry

Lab Home Page

Our group is interested in human and animal coronaviruses.  These viruses cause respiratory and gastrointestinal diseases.  In rare instances that depend on the infecting coronavirus strain, the age and the immune competence of the infected individual, disease can be life-threatening.   The severe acute respiratory syndrome (SARS) epidemic of 2003 was caused by a coronavirus.  Coronaviruses are known for their ability to transfer from infected animals to humans.  Understanding this so-called “xenotropism” requires further knowledge of steps in the infection process.  We use coronaviruses to dissect the related steps of virus assembly and virus entry.  Our current efforts focus on the ways that proteins extending from virus particles (the “spike” proteins forming the characteristic “corona”) operate to mediate cell entry.
