Understanding how the body fights against pathogen infections and immunity is a silent contest between humans and pathogens and how the body fights against pathogens is essential for health.
The following is an in-depth analysis of infection and immunization mechanisms:
1. Biological barriers and mechanical barriers: First and second line biological barriers to the immune system: consisting mainly of skin, mucous membranes and their secretions. These are acidic environments that can destroy the structure of the virus and render it non-active. At the same time, cells on the skin and mucous membranes are responsible for the direct killing of the virus through the management of substances such as antibacterium, soluble enzymes, etc. In addition, normal strains within the human body have to some extent inhibited the reproduction of the virus. Mechanical barriers: Composed of the physical structure of the skin and mucous membranes, as the most outer layer of protection to prevent pathogens such as viruses from entering the human body. When the virus attempts to invade through respiratory, digestive and other means, these barriers can play a powerful physical defensive role by keeping the virus out of the body.
II. Immunocellular Lines: Working in concert against viruses when the first two lines of the virus enter the human body, they play a key role. This includes immunosuppressive cells, such as megacormic cells, t-cells, and B-cells, which work together to fight against the virus’s invasion. Reconnaissance and alert: Once the virus enters the human body, it is first detected by immunosuppressive cells such as giants. These cells consume infected cells or viruses and digest them into antigen fragments. At the same time, they also release chemical signals (e.g. jammers, white cell media, etc.), alert other immunosuppressors and activate other immunosuppressors to put them in combat. Activation and amplification: Upon receipt of the alarm, immune cells such as T-cells and B-cells will be activated, their numbers will rapidly expand, they will be divided into effects T-cells and plasma cells, etc., and they will be prepared for the next battle. Co-operation in combat: Immunocellular cells, such as active T-cells and plasma cells, act in concert to attack the virus. Effects T cells can directly kill infected cells, while plasma cells can regenerate antibodies, bind to viruses and render them inactive. In addition, other immune cells, such as NK and neutral particle cells, are involved in the fight against the virus ‘ s invasion.
Immunization memory: The rapid response of the body to the pathogens has a strong memory function. When the immune system successfully resists virus intrusion, it produces memory T and memory B cells. This memory function makes the human body more resilient and adaptable to the virus. When these pathogen microorganisms re-invasive, the immune system is able to quickly identify and generate antibodies of a particular nature, for the purpose of resistance to infection.
IV. Immunisation Response: The dual protected natural immunisation response for natural immunisation and acquired immunisation: is the first line of defence for aerobody-to-otherth invasion, which is quick, wide-ranging but limited. It is a non-specific, immune response that can immediately confront pathogenic microorganisms, but has a limited impact. Acquiring immunity responds to specific pathogen microorganisms with a high degree of specificity. In this immune response, over time, the organism produces more specific antibodies, including those produced by B cells, and the cytotoxic effects of T-cells. By obtaining an immune response, the resulting antibodies are reminiscent of specific pathogens.
V. Vaccines: One of the important means of preventing viral infection is an effective means of preventing it. By inoculation, the human body can pre-empt the immunity of a virus. Pathogens in vaccines are treated in a special way, which deprives them of their pathogenicity but keeps them immune. When humans are vaccinated, the immune system recognizes and remembers the pathogens, and when a real virus invades, the immune system reacts quickly and removes the virus. In conclusion, infection and immunization are complex and sophisticated processes that involve multiple dimensions and mechanisms. Knowledge of these mechanisms helps us to better understand our bodies and to take appropriate measures to prevent infection and maintain health.
