Humoral immunity

These immune cells are present in the bone marrow and other lymphoid tissues. Antibodies are a key component of humoral immunity and provide protection through extracellular fluids. They are produced by plasma cells which originate from B lymphocytes. Antibodies are effective at dealing with extracellular (or freely circulating) pathogens. They have various functions…

which eventually causes the dead of many cells, especially central nervous cells (1)(3)(4). The inability to repair DNA breakage also affects the recombination process of T-cell receptors and Ig genes, which then results in the abnormal humoral and cell-mediated immunity. Symptoms Individuals…

differences between innate and adaptive immunity along with the chemical and physical factors that are involve in these immunities. It is easy to cluster the structures, cells, and chemicals that act against pathogens into two main lines of defense, each of which overlaps and reinforce each other. The first line of defense is composed chiefly of external physical barriers to pathogens, especially skin and mucous membranes. The second…

system, which is responsible for defending the body against pathogens, is a very complex and vital body system. The immune system involves both innate and adaptive immunity. Innate immunity functions as the “first responder” system of the body. The skin, the mucous membranes are the first line of defense in innate immunity. The skin and mucous membranes serve to prevent microbes from entering the body. If microbes enter the body, then the tears, saliva, urine flow, vaginal…

of airway smooth muscle. When the person Expose to an allergen the IgE antibodies level will increase. The change in IgE production is related to Th2 (these cells are not normally found in the lung, they also promote inflammation and increase humoral immunity by promoting antibodies production). IgE antibodies bind to receptors on mast cells. So when an allergen is inhaled and is in contact with mast cells, the release of…

pathogen. This immunity relies heavily on phagocytic cells such as neutrophils, basophils and macrophages that recognize pathogens and immediately act to destroy the foreign material. The second line of defense is known as adaptive immunity. This form of immunity is antigen-specific because it is capable of remembering a previous antigen. Because it is able to remember and recognize its previous foes, adaptive immunity can generate antibody-mediated immunity (AMI) and/or cell-mediated immunity…

found on epithelial cells, on smooth muscle cells, on keralino cytes, and on fibroblasts. The main function of CD40 is that it regulate a myriad spectrum of cellular and molecular processes such as progression and initiation of cellular and humoral adaptive immunity. In general, there are two families of the costimulatory molecules which are molecules from the CD28-B7 costimulatory…

Polio? Rather say dinosaurs. It is scary, dangerous, and extinct. What is this disease? Why only the parents of new born sweat for its vaccine for the tiny citizens of the Earth if it is eradicated? You are one of the two. One who knows about the polio because you lived in the time when it showed its colors and shook the world or that you are the one whose parents knows well enough, thus your body already bears the ‘protection’ and therefore vaccine. Let’s tell more than your queries about…

severe fibroproliferative vascular lesions of small arteries and arterioles, 2) excessive and often progressive deposition of collagen and other extracellular matrix macromolecules in skin and various internal organs, and 3) alterations of humoral and cellular immunity. 1 Numerous studies have suggested a sequence…

For example, the language used in modern medicine. In medicine, humoral immunity or humoral regulation is used when describing substances such as hormones and antibodies that circulate throughout the body. It also uses the term blood dyscrasia to refer to any blood disease or abnormality. Another example is personality tests ranging…
