Cellular Microbiology: Pathogen-Host Cell Molecular InteractionsDeletion of Interleukin-4 Receptor Alpha-Responsive Keratinocytes in BALB/c Mice Does Not Alter Susceptibility to Cutaneous LeishmaniasisThe skin microenvironment at the site of infection plays a role in the early events that determine protective T helper 1/type 1 immune responses during cutaneous leishmaniasis (CL) infection. During CL in nonhealing BALB/c mice, early interleukin-4 (IL-4) can instruct dendritic cells for protective Th1 immunity.
Fungal and Parasitic Infections | SpotlightPolymorphisms in Receptors Involved in Opsonic and Nonopsonic Phagocytosis, and Correlation with Risk of Infection in Oncohematology PatientsHigh-risk hematological malignancies are a privileged setting for infection by opportunistic microbes, with invasive mycosis being one of the most serious complications. Recently, genetic background has emerged as an unanticipated risk factor.
Cellular Microbiology: Pathogen-Host Cell Molecular InteractionsCandida albicans Ras1 Inactivation Increases Resistance to Phagosomal Killing by Human NeutrophilsHost phagocytic cells are crucial players in initial defense against Candida albicans infection. C. albicans utilizes MAP kinases and Ras1 stress response signaling pathways to protect itself from killing by immune cells.
Host Response and InflammationHeterogeneity of Ly6G+ Ly6C+ Myeloid-Derived Suppressor Cell Infiltrates during Staphylococcus aureus Biofilm InfectionMyeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature monocytes and granulocytes. While neutrophils (polymorphonuclear leukocytes [PMNs]) are classically identified as highly differentiated cells specialized for antimicrobial defense, our laboratory has reported minor contributions of PMNs to the immune response during Staphylococcus...
Host-Associated Microbial CommunitiesCeftriaxone Administration Disrupts Intestinal Homeostasis, Mediating Noninflammatory Proliferation and Dissemination of Commensal EnterococciEnterococci are Gram-positive commensals of the mammalian intestinal tract and harbor intrinsic resistance to broad-spectrum cephalosporins. Disruption of colonization resistance in humans by antibiotics allows enterococci to proliferate in the gut and cause disseminated infections.
Bacterial InfectionsTracking Anti-Staphylococcus aureus Antibodies Produced In Vivo and Ex Vivo during Foot Salvage Therapy for Diabetic Foot Infections Reveals Prognostic Insights and Evidence of Diversified Humoral ImmunityManagement of foot salvage therapy (FST) for diabetic foot infections (DFI) is challenging due to the absence of reliable diagnostics to identify the etiologic agent and prognostics to justify aggressive treatments. As Staphylococcus aureus is the most common pathogen associated with DFI, we aimed to develop a multiplex immunoassay of IgG in serum and medium enriched...
Microbial Immunity and VaccinesPreexisting Simian Immunodeficiency Virus Infection Increases Susceptibility to Tuberculosis in Mauritian Cynomolgus MacaquesTuberculosis (TB), caused by Mycobacterium tuberculosis, is the leading cause of death among human immunodeficiency virus (HIV)-positive patients. The precise mechanisms by which HIV impairs host resistance to a subsequent M. tuberculosis infection are unknown.
