Immune system

In spite of these difficulties, future research hinges on advances in the ability to selectively inhibit or control innate and adaptive Matthew Xin Mechanisms of Human Health and Disease 2015 Matthew Xin Mechanisms of Human Health and Disease 2015 immune functions, a promising field with applications in meningitis as well as many other autoimmune diseases. This paper will explore the pathophysiology of meningitis as a consequence of bacterial infection elsewhere in the body, as well as the history

Lupus is an autoimmune disease where your own immune system attacks not only pathogens, but your own healthy tissue. It is one of the more severe autoimmune diseases and can seriously impair the life of the sufferer if left untreated, possibly leading to death. Symptoms of the disease we now know as lupus were first described in the Middle Ages, though physicians of the time did not know the cause of the disease. French physician Pierre Cazenave was the first person to give a detailed description

i.e. our immune system, to fight and defend our body against a disease. When the vaccine is injected into our body, it will trigger an immune response in the same way our body would respond after an exposure to the virus, but without the person suffering symptoms of the disease. Our body 's immune system will detect and recognize the pieces of virus or the killed/weakened virus (also known as the antigen) in the vaccine as a foreign invader. Our immune system will then start an immune response

foreign cells, almost every cell has been built with certain identification tags, MHC markers. Those cells carrying antigens, a ?non-self? tag, are identified by the immune system. This helps insure that the immune system does not accidentally try to harm the body. Lymphocytes Lymphocytes are white blood cells that patrol the body for "non-self" tags. The number of these particular cells in the average body is approximately 1 trillion

Introduction The advancement of complicated molecular technology to distinguish microorganisms by their 16S rRNA profiles has resulted in renewed attention in the resident microorganisms as a possibility stimulant of immune-mediated inflammatory illnesses. An idea that can be followed back to the 19th century, when Wohlmann and Bannatye proposed the inflammation of joints may be resulting from a Mycobacterium (Yeoh et al. 2013). Evidence proceeds to emerge to indicate that commensal microorganisms

An immune system disorder causes abnormally low activity or over activity of the immune system. In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections. An autoimmune disease develops when your immune system, which defends your body against disease, decides your healthy cells are foreign. Thus, your immune system attacks healthy cells

Coeliac disease Overview Celiac disease (gluten-sensitive enteropathy), sometimes called sprue or coeliac, is an immune response to eating gluten. people with coeliac disease who eat gluten, the immune system reacts ab`normally in your small intestine. Causing small bowel damage. The tiny, finger-like projections which line the bowel called villi become inflamed and flattened. This is referred to as villous atrophy. Villous atrophy reduces the surface area of the bowel used for nutrients absorption

how vaccines work, I found the CDC’s article thoroughly explaining the fundamentals of vaccines. Basically, “Vaccines help develop immunity by imitating an infection. This type of infection, however, does not cause illness, but it does cause the immune system to produce T-lymphocytes and antibodies.” By infecting yourself with a weakened infection, you essential gave your body a guide on how to defend if the real deal came through. Now this is where the

endocrine theory proposes that the endocrine system is largely responsible for the ageing process as it regulates hormones in the body. As humans age chronologically, their systems become more ineffective leading to changes in the body such as menopause. These changes subsequently cause biological ageing. The evidence to support this theory was collected by conducting an experiment on mice in which the pituitary gland (controlling the endocrine system) was removed. The mice were given the necessary

Immune system attacking the thyroid The immune system is consisted of cells and tissues throughout the whole body. They work together to defend your body from any types of invasion and infections. Problems with the immune system can cause the immune system to mistaken the healthy body cells as invaders and will repeatedly attack the cells; this is known as an autoimmune disease. An example of this disease is the Hashimoto’s thyroiditis, where the immune systems mistakenly recognizes the thyroid cells
