Antibodies, function, types and relationship to Covid 19 virus
The germs are found everywhere. They inhabit water, wind, food, plants, and even the human body. Rather, the immune system with its parts, including this antibody, is a pivotal role in preventing the swelling of these bacteria, which reduces the abnormalities of abrasion. Therefore, it is necessary to know what are the antibodies, their functions, and how and how to support their role in the forces opposing pathogens.
What are antibodies?
Also known as immunoglobulin, and it is made of a protective protein that the immune system produces as a reaction due to the presence of a foreign substance or bacteria in the body called the antigen, as the specialized white blood cells known as lymphocytes produce antibodies, which in turn determine these antigens and adhere to them with the aim of Destroy it until the body recovers.
It performs three basic functions:
The release of antibodies into the blood and mucous membranes is stripped, as they adhere to and destroy foreign bodies such as pathogens and toxins. It activates the complementary pattern of destruction of bacterial cells by decomposition by holes in the cell wall. The swallowing process is facilitated by phagocytosis by phagocytic cells.
It can be installed in five types according to its activity and its fixed region. Each pattern is strategized with a letter attached to abbreviate the word immunoglobulin as follows: IgG, IgM, IgA, IgD and IgE
This variety plays a major role in protecting the body against pathogens that attack the body by inhalation or swallowing, and it is present in overwhelming proportions in the mucous membranes such as the mucous membranes of the lungs and nasal sinuses, saliva, tears, breast milk, and intestinal fluids.
This role crystallizes the role of these bodies in guarding cells from foreign bodies and preventing them from coming to internal users, as it is the largest protection line for your body in the face of infections. This class is the largest among other forms, and it represents about 5% of all antibodies present in the blood.
They are present in varying body fluids, as they constitute about seventy-75% of all antibodies present in the blood and other body fluids, and given their small size and high readiness to spread, they move easily in cells, and their role in protecting the body versus foreign particles crystallizes by remembering the germs That she was subjected to before. IgG is the single antibody that can cross the placenta and thus provides negative immunity to the fetus and infants in the first few months of life.
For IgE objects
This type of body works to protect the body from parasitic diseases as it is noticeably concentrated in the context of coming to allergens such as dust, pollen, animal dander, and allergens.
Regardless of the fact that its exact method of operation is not intuitive until this moment, it is only found in sizes that are few in the fibers that line the abdomen or chest.
The tests required to detect immunoglobulin of Covid 19 virus
Analyzes of detection of the immunoglobulin of Covid 19 virus are based on IgG and IgM type tests that the body generates in response to SARS-CoV-2 infection.
