Eukaryotic protein mimicry as an infection strategy for Ehrlichia chaffeensis
Ehrlichia chaffeensis (E. ch.) expresses the TRP120 multifunctional effector on the surface of infectious dense-cored ehrlichiae which is known to play a role in phagocytic entry, but a cognate host receptor has not been identified. We recently reported that E. ch. activates canonical Wnt signaling …

Ehrlichia chaffeensis Activates Notch Signaling Through SLiM Mimicry to Inhibit Apoptosis
Ehrlichia chaffeensis is a small, obligately intracellular gram-negative bacterium, and the etiological agent of human monocytotropic ehrlichiosis (HME), an emerging, life threatening tick-borne zoonosis. E. chaffeensis infects mononuclear phagocytes and has evolved molecular strategies to …

Ehrlichia chaffeensis Type 1 Secreted Effector TRP47 is a Novel SUMOylated Nucleomodulin
Ehrlichia chaffeensis secretes immunodominant and immunoprotective protein effectors into the host cell using a type I secretion system. The best-characterized of these effectors are the tandem repeat proteins (TRPs). In this study, E. chaffeensis TRP47 was identified as a target for host cell …

TRP75-Mediated STAT3 Activation Promotes Anti-Apoptotic Signaling and Ehrlichia chaffeensis Infection
Ehrlichia chaffeensis is an obligately intracellular bacterium that manipulates mononuclear phagocytes by hijacking host cell signaling pathways to promote infection. In part, E. chaffeensis accomplishes host cell manipulation through the actions of secreted effector proteins, including the tandem …

Host-Dependent Expression, Transcriptional Regulation and Protection of Ehrlichia chaffeensis Tandem Repeat Proteins
Ehrlichia chaffeensis is an obligately intracellular bacterium that is the causative agent of human monocytotropic ehrlichiosis, an emerging life-threatening zoonosis. E. chaffeensis is transmitted by the lone star tick, Amblyomma americanum, and replicates in mononuclear phagocytes in mammalian …

Ehrlichia chaffeensis E3 Ligase TRP120 Ubiquitinates Tumor Suppressor FBW7 for Degradation to Promote Infection
Ehrlichia chaffeensis (E. chaffeensis) exploits evolutionarily conserved Notch and Wnt host cell signaling pathways to downregulate innate immune host defenses and promote infection. The multifunctional E. chaffeensis TRP120 effector which has HECT E3 ubiquitin ligase activity, interacts with the …

The role of the P28 multigene family in the pathogenesis of Ehrlichia chaffeensis infection.
<i>Ehrlichia chaffeensis</i> is a gram-negative obligate intracellular bacterium which parasitizes cells of the monocyte/macrophage lineage in mammals. <i>E. chaffeensis</i> possesses a unique cell wall that lacks LPS and the classical peptidoglycan found in other gram-negative bacteria. …

Ehrlichia chaffeensis mediates Hedgehog and Hippo signaling to activate an anti-apoptotic cellular program
Ehrlichia chaffeensis is a gram-negative intracellular bacterium responsible for the emerging zoonotic disease, human monocytic ehrlichiosis (HME). HME is the most prevalent and life-threatening tick-borne disease in the United States. In the past two decades, the incidence of HME has increased …

Ehrlichia chaffeensis TRP32 is a Nucleomodulin that Regulates Host Gene Expression and Post-Translational Modifications Determine its Localization and Function
Ehrlichia chaffeensis is an obligately intracellular bacterium that reprograms the mononuclear phagocyte through diverse effector-host interactions to modulate numerous host cell processes, including transcription. Previously, we reported that E. chaffeensis TRP32, a type 1 secreted effector, …

Ehrlichiosis: Understanding immune mechanisms that lead to the development of fatal disease
The clinical manifestations of HME caused by Ehrlichia chaffeensis, a Gram-negative, LPS-lacking bacterium, including toxic shock-like syndrome and liver injury in the absence of overwhelming bacterial burdens, has led to the hypothesis that severe disease is immune-mediated. Our previous studies …
