Breed variability in the cellular mediated immune response to experimental Neospora caninum infection in heifers
Protozoan parasite Neospora caninum causes abortion in infected cattle while others remain asymptomatic. Host immunity plays a critical role in the outcome of bovine neosporosis. Despite extensive research, there is a critical gap in therapeutic and preventive measures, and no effective vaccines are available. Both beef and dairy cattle can suffer from N. caninum-induced abortions, but cumulative evidence suggests a breed susceptibility being higher in dairy compared with beef breeds. It has been established that the response to N. caninum infection primarily involves a cell-mediated immune response (CMIR) regulated by T-helper type 1 (Th1) cells and specific cytokines. The delayed-type hypersensitivity (DTH) skin test has been used to measure the ability of livestock to generate CMIR, in the context of breeding for disease resistance and as a method for diagnosis of several diseases. In this study, we evaluated the immune response triggered by an N. caninum-induced DTH skin test between Holstein – a dairy breed intensively selected- and Argentinean Creole heifers – a beef breed with minimal genetic selection- to assess differences in CMIR following experimental N. caninum infection. The immune response, measured through skinfold thickness and histological and immune molecular analysis, revealed variations between the breeds. Our study found an increased CMIR in Argentinean Creole heifers compared to Holstein heifers. Differential gene expression of key cytokines was observed at the DTH skin test site. Argentinean Creole heifers exhibited elevated IFN-γ, IL-12, IL-10, and IL-4, while Holstein heifers only showed higher expression of IL-17. This finding could underscore genetic diversity in response to neosporosis, which could be used in breeding cattle strategies for disease resistance in cattle populations.
期刊介绍：
The journal reports basic, comparative and clinical immunology as they pertain to the animal species designated here: livestock, poultry, and fish species that are major food animals and companion animals such as cats, dogs, horses and camels, and wildlife species that act as reservoirs for food, companion or human infectious diseases, or as models for human disease.
Rodent models of infectious diseases that are of importance in the animal species indicated above,when the disease requires a level of containment that is not readily available for larger animal experimentation (ABSL3), will be considered. Papers on rabbits, lizards, guinea pigs, badgers, armadillos, elephants, antelope, and buffalo will be reviewed if the research advances our fundamental understanding of immunology, or if they act as a reservoir of infectious disease for the primary animal species designated above, or for humans. Manuscripts employing other species will be reviewed if justified as fitting into the categories above.
The following topics are appropriate: biology of cells and mechanisms of the immune system, immunochemistry, immunodeficiencies, immunodiagnosis, immunogenetics, immunopathology, immunology of infectious disease and tumors, immunoprophylaxis including vaccine development and delivery, immunological aspects of pregnancy including passive immunity, autoimmuity, neuroimmunology, and transplanatation immunology. Manuscripts that describe new genes and development of tools such as monoclonal antibodies are also of interest when part of a larger biological study. Studies employing extracts or constituents (plant extracts, feed additives or microbiome) must be sufficiently defined to be reproduced in other laboratories and also provide evidence for possible mechanisms and not simply show an effect on the immune system.
