“Background Leishmaniasis is a vector-borne disease transmitted exclusively by sand fly bites [1], during which the host is inoculated with saliva. The saliva has been shown to downregulate the
immune response allowing the establishment of successful pathogen infection [2–4]. Co-injection of Leishmania and salivary gland homogenates from either Lutzomyia longipalpis or Phlebotomus papatasi in naïve mice produces a substantial increase in lesion size and parasite burden. The increase in infectivity was associated with the capacity of the saliva to selectively inhibit antigen presentation and nitric oxide Diflunisal (NO) and hydrogen peroxide production thus inhibiting the ability of macrophages to kill the intracellular parasites [5, 6]. Furthermore, Leishmania vector saliva inhibits the production of protective type 1 cytokines such IL-12 and IFN-γ [7–9], while enhancing the production of interleukin (IL)-10, IL-4, IL-6 and prostaglandin E (PGE)2, all of which enhance parasite survival [10–13]. Pre-exposure to saliva or bites from uninfected sand flies can lead to an increase in host resistance to Leishmania as a consequence of developing a long-term humoral immune response against the salivary components responsible for pathogen establishment [14].
