Masters (Immunology). May, 2004. 63 pages. 2 tables, 10 figures. 55 titles. This research converged on T cell responses to respiratory agents, tobacco smoke and allergens in humans, and T cell responses to an extracellular bacterium, M. bovis, in calves. In the first chapter, we will discuss the basic functions of the immune system. In the second chapter, we will discuss the basic functions of the immune system. In the second chapter, we characterized the impact of tobacco smoke on T cell responses in atopic smokers and atopic nonsmokers. The results were inconclusive and the study was postponed until the proper allergens were found. We also characterized the T cell responses of calves infected with Mycoplasma bovis in the third chapter. The results showed an increase in T lymphocytes in the upper respiratory tract of infected calves, which correlated with sites of infection.application/pdfenAllergy and ImmunologyCell and Developmental BiologyCellsImmunityImmunology and Infectious DiseaseLife SciencesMedical Cell BiologyMedical ImmunologyMedical ToxicologyMedicine and Health SciencesOther Cell and Developmental BiologyRespiratory SystemRespiratory Tract DiseasesToxicologyT cell responsesrespiratory tractM. bovisextracellular bacteriumtobacco smokeallergensimmune systemmycoplasma boviscalvessmokersnonsmokersThesis
