In a report to be published in the journal Cell Host & Microbe online June 11, researchers showed that immune - system - triggering TB proteins, or antigens, were able to prompt a larger,
prolonged immune system response just by being transported from infected dendritic cells to uninfected ones.
While a brief, acute
response to a suspected trigger may cause temporary physiological changes, the effects of chronic,
prolonged stress in dogs can long term undermine the dog's
immune system.
