Muscle Mass And Immune Function In The Senior Horse, Alisa Christina Herbst
Muscle Mass And Immune Function In The Senior Horse, Alisa Christina Herbst
Theses and Dissertations--Veterinary Science
Senior horses (≥ 15 years) represent up to one-third of the global equine population, and the proportion of old horses (≥ 20 years) in the U.S. has been steadily increasing. Aging is associated with a loss of skeletal muscle mass in horses, and while age-related muscle loss is comparingly well characterized in humans, little is currently known concerning underlying mechanisms, adverse outcomes, or the prevalence of low muscle mass in senior horses. One factor proposed to play a role in the development of age-related muscle atrophy in humans is inflamm-aging, a low-grade inflammation that affects elderly people and that has …
Modeling The Adaptive Immune Response To Mutation-Generated Antigens, Rory J. Geyer
Modeling The Adaptive Immune Response To Mutation-Generated Antigens, Rory J. Geyer
University Scholar Projects
Somatic mutations may drive tumorigenesis or lead to new, immunogenic epitopes (neoantigens). The immune system is thought to represses neoplastic growths through the recognition of neoantigens presented only by tumor cells. To study mutations as well as the immune response to mutation-generated antigens, we have created a conditional knockin mouse line with a gene encoding, 5’ to 3’, yellow fluorescent protein (YFP), ovalbumin (which is processed to the immunologically recognizable peptide, SIINFEKL), and cyan fluorescent protein (CFP), or, YFP-ovalbumin-CFP. A frame shift mutation has been created at the 5’ end of the ovalbumin gene, hence YFP should always be expressed, …

Role Of Pi3k-Akt Pathway In The Age Associated Decline In Tlr Mediated Activation Of Innate And Adaptive Immune Responses, Mosoka Papa Fallah
Role Of Pi3k-Akt Pathway In The Age Associated Decline In Tlr Mediated Activation Of Innate And Adaptive Immune Responses, Mosoka Papa Fallah
University of Kentucky Doctoral Dissertations
Immunosenescence results in reduced immune response to infections with Streptococcus pneumoniae as well as to pneumococcal polysaccharide vaccines. The antibody response to the capsular polysaccharide (CPS) provides protection against S. pneumoniae infection. CPS immunoresponse is T cell independent and needs the macrophage-derived cytokines such as IL-12, IL-6 and IL-1β to elicit an antibody response. We showed a cytokine dysregulation, i.e. a decrease in IL-12, IL-6 and TNF-α but an increase in IL-10, in the aged (18-24 months old comparable to >65 years in human) compared to young adult mouse (8-12 weeks less than 65 years old) splenic macrophages (SM) or …
