HIV and your Immune System - Your immune system is used to fight bacteria and viruses and it helps to keep you healthy. Sometimes your immune system can develop lymph and immune system disorders. What happens is your immune system can become over active or it can become weak chancing your bodies response to bacteria and viruses. If you are born with an immunodeficiency disorder it is called primary immunodeficiency if you develop it later in life it is called acquired immunodeficiency (UOR Medical Center, 2014). When the immune system over reacts it will start to attack and produce antibodies, which results in damaging its own tissues....   [tags: lymp, immune system]

Coevolution of Bacterial Gut Microbiota and the Human Adaptive Immune System - Within the gastrointestinal tract of the human body thrive trillions of bacteria, comprising what is known as the microbiota (Slack et al. 2009, Figure 1). The microbiota can be defined as the combination of microorganisms living simultaneously in a location, with that location being the human body (Round et al. 2009). Many years of evolution have contributed to the relationship that is observed between human intestinal bacteria and the adaptive immune system. Contrary to the common belief that all intestinal bacteria are pathogenic, recent evidence suggests that the bacteria residing in the human gut actually play a crucial role in human adaptive immunological function....   [tags: human gut, immune system, microbiota]
