Chemokines and their receptors play a critical role in orchestrating immunity to microbial pathogens, including the orally acquired Th1-inducing protozoan parasite Toxoplasma gondii. Chemokine receptor CXCR3 is associated with Th1 responses, and here we use bicistronic CXCR3-eGFP knock-in reporter mice to demonstrate upregulation of this chemokine receptor(More)
Leishmania donovani is a parasite that causes visceral leishmaniasis by infecting and replicating in macrophages of the bone marrow, spleen, and liver. Severe anemia and leucopenia is associated with the disease. Although immune defense mechanisms against the parasite have been studied, we have a limited understanding of how L. donovani alters(More)
Leishmaniasis is a clinically and epidemiologically diverse zoonotic disease caused by obligatory, intracellular protozoan parasites of the genus Leishmania. Cutaneous leishmaniasis is the most widely distributed form of the disease characterized by skin lesions. Leishmania aethiopica is considered the predominant etiological agent in Ethiopia. The current(More)
Numerous disease-causing parasites must invade host cells in order to prosper. Collectively, such pathogens are responsible for a staggering amount of human sickness and death throughout the world. Leishmaniasis, Chagas disease, toxoplasmosis, and malaria are neglected diseases and therefore are linked to socio-economical and geographical factors, affecting(More)
A commentary on Inflammatory cytokine and microRNA responses of primary human dendritic cells cultures with Helicobacter pylori strains by Hocès de la Guardia, A. Host cell interactions with bacterial pathogens trigger a wide variety of complex cellular signaling pathways that ultimately determine disease outcome. These inflammatory signaling cascades can(More)
Chronic inflammation of the intestinal mucosa is characteristic of inflammatory bowel diseases such as ulcerative colitis and Crohn's disease. Helminth parasites have developed immunomodulatory strategies that may impact the outcome of several inflammatory diseases. Therefore, we investigated whether Taenia crassiceps infection is able to decrease the(More)
All authors have no conflicts of interest to declare. ABSTRACT Ibrutinib (PCI-32765) is an irreversible dual Btk/Itk inhibitor shown to be effective in treating several B cell malignancies. However, limited studies have been conducted to study the effect of this drug on myeloid cell function. Hence, we studied the effect of 3 ibrutinib treatment on TLR-4(More)
Our increased understanding of host pathogen interactions shows that pathogens could capitalize on host cell pathways to favor entry and disease establishment. One such pathway used by Leishmania mexicana to enter into neutrophils and macrophages is the PI3Kγ signaling pathway. We recently showed that the use of the PI3Kγ inhibitor AS-605240 for the(More)
Ibrutinib, a BTK inhibitor, is currently used to treat various hematological malignancies. We evaluated whether ibrutinib treatment during development of murine bone marrow-derived dendritic cells (DCs) modulates their maturation and activation. Ibrutinib treatment increased the proportion of CD11c(+) DCs, upregulated the expression of MHC-II and CD80 and(More)
BACKGROUND Cutaneous leishmaniasis (CL) is a major public health concern in Turkey and Sanliurfa represents the most endemic city in Turkey. Although children are most commonly affected by CL, detailed studies of pediatric CL in Turkey are lacking. METHODOLOGY/PRINCIPAL FINDINGS In this report we retrospectively evaluated clinical and epidemiological data(More)
