Summary
Salmonella typhimurium is an important pathogen in both developed and developing countries where it causes significant HIV-linked morbidity. There is a pressing need to understand how immunity might be established against this organism that will function when the patient is immunocompromised either through age or through a comorbidity like HIV.

Summary
A particular kind of white blood cell, called a T lymphocyte, is responsible for controlling our immune responses to foreign invaders. These cells develop in the thymus, where they learn to distinguish between foreign invaders and self tissue, before emigrating to other organs. The regulation of this process is important to maintain a pool of T lymphocytes in the body. It is important that T lymphocytes do not respond against self tissue, as this can lead to a Oself destructO disease called auto ....A particular kind of white blood cell, called a T lymphocyte, is responsible for controlling our immune responses to foreign invaders. These cells develop in the thymus, where they learn to distinguish between foreign invaders and self tissue, before emigrating to other organs. The regulation of this process is important to maintain a pool of T lymphocytes in the body. It is important that T lymphocytes do not respond against self tissue, as this can lead to a Oself destructO disease called autoimmunity. Since these developing T lymphocytes will not see all kinds of self tissue while in the thymus, we propose that their education to prevent self-tissue reactivity may continue for some time after they leave the thymus.Read moreRead less
