| Popis: | Leishmaniases are a group of vector-borne parasitic diseases transmitted through the infected sand flies. Leishmania parasites are inoculated into the host skinalong with sand fly saliva. The sand fly saliva consists of biologically active molecules with anticoagulant, anti-inflammatory, and immunomodulatoryproperties. Such properties help the parasite circumvent the host's immune responses. The salivary compounds support the survival and multiplication of the parasite and facilitate the disease progression. It is documented that frequent exposure to uninfected sand fly bites produces neutralizing antibodies against specific salivary proteins and further activates the cellular mechanisms to prevent the establishment of the disease. The im- mune responses due to sand flysaliva are highly specific and depend on the composition of the salivary molecules. Hence, thorough knowledge of these compounds in different sand flyspecies and information about their antigenicity are paramount to designing an effective vaccine. Herein, we review the composition of the sand fly saliva,immunomodulatory properties of some of its components, immune responses to its proteins, and potential vaccine candidates against leishmaniases. |
