Implications of autophagy on arbovirus infection of mosquitoes

Arthropod-borne (arbo-) viruses, like all viruses, are obligate intracellular parasites that have evolved mechanisms to subvert cellular processes and evade anti-viral defenses to replicate and persist. An increasing body of research is beginning to recognize the intimate relationship between arboviruses and the cellular autophagy pathway. As a result, new therapeutic approaches that modify the autophagic response to viral infection have shown great promise. The preponderance of work thus far, however, has originated from vertebrate systems. Efforts to elucidate the role of autophagy during arbovirus infection of invertebrates have emerged, providing new insights into arbovirus-vector interactions; interactions that could be exploited for novel control strategies.
