Abstract

biting midges serve as vectors of pathogens affecting humans and domestic animals. is a vector of several arboviruses in North American that cause substantial economic losses to the US livestock industry. Previous studies showed that saliva, like the saliva of many hematophagous arthropods, contains numerous pharmacological agents that affect hemostasis and early events in the inflammatory response, which may enhance the infectivity of -borne pathogens. This paper reports on the immunomodulatory properties of salivary gland extracts on murine immune cells and discusses the possible immunomodulatory role of saliva in vesicular stomatitis virus infection of vertebrate hosts. Splenocytes treated with mitogens were significantly affected in their proliferative response, and peritoneal macrophages secreted significantly less NO. A 66-kDa glycoprotein was purified from salivary gland extract, which may be in part responsible for these observations and may be considered as a vaccine candidate.
