Humoral immunity (also called the antibody-mediated system) is the aspect of immunity that is mediated by macromolecules (as opposed to cell-mediated immunity) found in extracellular fluids such as secreted antibodies‚ complement proteins and certain antimicrobial peptides. Humoral immunity is so named because it involves substances found in the humours‚ or body fluids. The study of the molecular and cellular components that comprise the immune system‚ including their function and interaction‚ is the

From Celiac Disease to general distaste‚ gluten-free diets are on the rise and it may seem to some that the appearance and prevalence of gluten-sensitivity is a modern phenomenon‚ cashing in on a Western trend without a real scientific base. It may surprise the cautious reader to discover that Celiac Disease is in fact one of the most common long-term diseases worldwide with a history likely dating back to at least the first and second centuries. This begs the question: what is celiac disease? Where

Does wheat cause gut inflammation? By Liji Thomas‚ MD Inflammation is a pathway triggered by the exposure of the innate immune system to injury‚ infections or noxious stimuli. Sustained exposure or abnormal continuous activation of the immune cells to such stimuli can lead to chronic inflammation. Such a condition is characterized by elevated levels of proinflammatory serum markers including the interleukins‚ acute phase proteins and interferons. The reasons for such prolonged inflammatory responses

the Immune System chapter 1 T defense system that has evolved to protect animals from invading pathogenic microorganisms and cancer. It is able to generate an enormous variety of cells and molecules capable of specifically recognizing and eliminating an apparently limitless variety of foreign invaders. These cells and molecules act together in a dynamic network whose complexity rivals that of the nervous system. Functionally‚ an immune response

SLE can affect various organs of the body‚ on people of both sexes‚ all ages and all ethnic groups(7). Despite of the progression in the current knowledge in molecular pathogenesis of SLE‚ the exact etiology of the disease still remained elusive. In recent experimental and clinical studies abnormal stimulation of innate immunity involving
