Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune‐Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis [PDF]
Parasite Immunology, Volume 48, Issue 3, March 2026.ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.
