EphrinA2 Receptor (EphA2) Is an Invasion and Intracellular Signaling Receptor for


Chlamydia trachomatis are major human pathogens causing ocular and sexually transmitted diseases with hundreds of millions of cases per year. Chlamydia replicate inside the host cell in a membrane bound vacuole called inclusion. The current concept on how Chlamydia communicates with the host cell during its replication is based on the identification of the host protein that interacts with Chlamydia. Here, we describe that C. trachomatis-serovar L2 and D use EphA2, a member of the largest class of human receptor tyrosine kinases, as an adherence and entry receptor that is endocytosed together with the bacteria. Cell surface EphA2 receptor is adopted by Chlamydia to function also at the inclusion to support growth and replication and to keep the infected cell in an apoptosis resistant state. Thus, we show that EphA2 is an undiscovered important surface and intracellular signaling receptor that is crucial for chlamydial infection and development.
