The Dominance of Coinfecting Parasites' Indirect Genetic Effects on Host Traits.

AbstractIndirect genetic effects (IGEs) exist when there is heritable variation in one organism's ability to alter a second organism's traits. For example, parasites have antigens that can induce a host immune response, as well as disparate strategies to evade or suppress host immunity; among-parasite genetic variation in these antigens generates among-host variation in immune traits. Here, we experimentally show that the cestode parasite exerts an IGE on an immune trait (peritoneal fibrosis) in its threespine stickleback host: stickleback developed strong fibrosis after exposure to some parasite genotypes but not others.

Evaluation of nonpolar lipid extract antigen-based enzyme-linked immunosorbent assay for the serodiagnosis of tuberculosis.

This study assessed the diagnostic potential of nonpolar lipid extracts in enzyme-linked immunosorbent assays (ELISAs) for tuberculosis (TB) serodiagnosis. Nonpolar lipid extracts were harvested from Mycobacterium tuberculosis (Mtb) knockout in mce1 operon (∆mce1) and its parental wild type (WT) strains. IgM and IgG anti-nonpolar lipid serum levels were measured in TB patients (n=45), healthy individuals with positive (n=22) and negative (n=44) interferon-gamma release assay (IGRA) results, and symptomatic respiratory (SR) patients with negative TB tests (n=9).

Impaired macrophage and memory T-cell responses to Bacillus Calmette-Guerin nonpolar lipid extract.

Introduction: The attenuation of BCG has led to the loss of not only immunogenic proteins but also lipid antigens.

Methods: Thus, we compared the macrophage and T-cell responses to nonpolar lipid extracts harvested from BCG and () to better understand the role of BCG lipids in the already known diminished responses of the vaccine strain.

Results: Relative to Mtb, nonpolar lipid extract from BCG presented a reduced capacity to trigger the expression of the genes encoding TNF, IL-1b, IL-6 and IL-10 in RAW 264.

Ameliorating the impairment of glucose utilization in a high-fat diet-induced obesity model through the consumption of Tucum-do-Cerrado (Bactris Setosa Mart.).

Introduction: We evaluated the effect of Tucum-do-Cerrado on glucose metabolism homeostasis and its relationship with redox-inflammatory responses in a high-fat (HF) diet-induced obesity model.

Results: The HF diet increased energy intake, feed efficiency, body weight, muscle and hepatic glycogen, insulin, homeostatic model assessment of insulin resistance (HOMA IR) and beta (β)-cell function, and gut catalase (CAT) activity, and decreased food intake, hepatic glutathione reductase (GR), glutathione peroxidase (GPX), glutathione S-transferase (GST), and superoxide dismutase (SOD) activities, hepatic phosphoenolpyruvate carboxykinase 1 (Pck1), and intestinal solute carrier family 5 member 1 (Slc5a1) mRNA levels compared with the control diet. However, the HF diet with Tucum-do-Cerrado decreased hepatic glycogen, and increased hepatic GR activity, hepatic Slc2a2 mRNA levels and serum Tnfa compared with the HF diet.

All the analyses were performed for total population, also stratified for sex and age.

Prostaglandin E2 contributes to survival and therapeutic failure in cutaneous leishmaniasis.

Patients with cutaneous leishmaniasis (CL) present an exacerbated inflammatory response associated with tissue damage and ulcer development. In recent years, higher rates of failure to pentavalent antimoniate therapy have been observed, yet the underlying reason remains poorly understood. We hypothesize that the eicosanoid PGE2 favours the establishment of infection by , which contributes to therapeutic failure.

Dogs Harbor and Participate in the Transmission Cycle of Human Tegumentary Leishmaniasis.

Dogs play an important role in transmission of , but epidemiologic and clinical studies of canine tegumentary leishmaniasis (CTL) are scarce. In an endemic area of human American tegumentary leishmaniasis (ATL) caused by we determine the prevalence and incidence of both CTL and subclinical (SC) infection in dogs and evaluated if the presence of dogs with CTL or SC infection is associated with the occurrence of human ATL. SC infection in healthy animals and CTL in animals with ulcers were determined by PCR on biopsied healthy skin or on ulcers or by detecting antibodies against soluble leishmania antigen.

NKG2D promotes CD8 T cell-mediated cytotoxicity and is associated with treatment failure in human cutaneous leishmaniasis.

Cutaneous leishmaniasis exhibits a spectrum of clinical presentations dependent upon the parasites' persistence and host immunopathologic responses. Although cytolytic CD8 T cells cannot control the parasites, they significantly contribute to pathologic responses. In a murine model of cutaneous leishmaniasis, we previously found that NKG2D plays a role in the ability of cytolytic CD8 T cells to promote disease in leishmanial lesions.
