Rickettsia rickettsii encodes a secretory lipase that facilitates intracytosolic colonization in host cells.

Mohammad Sadik, Imran Moin, Saif Ullah, Andrew C. Krusenstjerna, Mathilde Gonin, Erin D. Goley, Mohammad Sayeedur Rahman, Oliver H. Voss

This study identifies RLip, a conserved lipase in Rickettsia rickettsii, which facilitates intracytosolic colonization by enabling escape from phagolysosomal fusion.

Phosphatidylserine-binding receptor, CD300f, on macrophages mediates host invasion of pathogenic and non-pathogenic rickettsiae.

Oliver H. Voss, Imran Moin, Hodalis Gaytan, Mohammad Sadik, Saif Ullah, Mohammad Sayeedur Rahman

This study identifies CD300f as a receptor on macrophages that mediates engulfment of rickettsiae, with loss of CD300f protecting against infection.
