A hallmark of immune reponses is memory for specific antigens that have triggered immune responses in the past. Immunological memory is due to the presence of a long- lasting antibodies and very long-lived lymphocytes that arise during proliferation and differentiation of antigen-stimulated B cells anf T cells. Every new encounter with the same anigen results in a rapid proliferation of memory cells. Therefore the antibody titer is far more greater than during a primary response and consist mainly of IgG antibodies. This secondary response.
A fever can help the body's immune response by making it harder for bacteria and viruses to survive and reproduce. It also helps the immune system work more efficiently to fight off infections.
it is a lymphocytes that plays a large role in humeral immune response. It also helps in making antibodies.
adjuvants are substances that when mixed with isolated antigen,increases its immunogenicity,thereby provoking inflammation and draws large number numbers of immune system cells to the site of injection.
The immune system must attack the bodys own cells
Vaccines work by stimulating the immune system to create a response against a specific pathogen. However, protozoa, being complex organisms, have different mechanisms of evading the immune response compared to bacteria or viruses. Developing vaccines against protozoal diseases is challenging because of the complexity of protozoa and their ability to change their surface proteins, making it difficult for the immune system to recognize and target them effectively.

Primary versus Secondary Immune ResponseThe primary immune response occurs the first time that the immune system comes in contact with the antigen. During this time the immune system has to learn to recognize antigen and how to make antibody against it and eventually gain immunological memory. This primary response takes time (about two weeks) and during this time the person experiences signs of illness. IgM antibodies are the hallmark of a new infection because they are the first antibodies made when a person is exposed to an antigen for the first time. After the body learns to make IgM antibodies, it will start making IgG antibodies to the antigen.The secondary immune response occurs the second time (3rd, 4th, etc.) the person is exposed to the same antigen. At this point immunological memory has been established and the immune system can start making antibodies immediately. The antigen usually is killed within minutes and the person is not aware that he/she was attacked. The antibodies in this response are IgG and IgA or (in the case of allergy IgE).

Stroke can significantly impact the immune system by triggering a systemic inflammatory response. This response can lead to the activation of immune cells and the release of pro-inflammatory cytokines, which may contribute to further brain injury and complications. Additionally, stroke can cause immune suppression, making the body more susceptible to infections, particularly in the respiratory and urinary tracts. Overall, the dual nature of the immune response following a stroke can complicate recovery and influence long-term outcomes.
The thymus gland in pigs is responsible for the production of T lymphocytes, which are a type of white blood cell essential for the immune response. The thymus gland plays a crucial role in the development and maturation of the immune system in pigs.
because HIV, AIDS attacks your body's immune system. You know the system responsible for fighting off infections and making it possible for wounds to heal and such. When there is no immune system response to a virus or infection, then said virus or infection takes over rendering the body defenseless.
it is a lymphocytes that plays a large role in humeral immune response. It also helps in making antibodies.
Antigenic variation is a mechanism used by certain pathogens, such as viruses and bacteria, to change their surface antigens, making it difficult for the immune system to recognize and mount an effective response against them. This allows the pathogen to evade immune detection and establish persistent infections in the host.
Not particularly - the B cell is the class of lymphocyte that is responsible for making antibodies and a certain subclass of B cells are the "memory cells" that retain the ability to make useful and needed antibodies in case of exposure to the same pathogen again. A vaccination is not likely to do a person with B cell deficiencies much good - they can mount a weak T cell based immune response, but without B cells to activate the T cells and modulate the immune response, it will be pretty weak.
Fasting can weaken the body's immune system, making it harder to fight off a cold. When you fast, your body may not get enough nutrients and energy to support a strong immune response, making you more susceptible to getting sick. It's important to maintain a balanced diet to support your immune system, especially during cold and flu season.
