Fever, Inflammatory myopathies, and vitamin A deficiency.
Cytokines are special proteins that direct immune and inflammatory responses in the body. They act as messengers between different cells of the immune system, regulating their activities in response to infections and other stimuli. Examples include interleukins, interferons, and tumor necrosis factor.
Examples of immunoglobulins include IgG, IgA, IgM, IgE, and IgD. Each type of immunoglobulin plays a different role in the immune system, such as neutralizing pathogens, promoting immune responses, or triggering allergic reactions.
antigens
The adaptive immune system was developed in higher vertebrates to combat pathogens and antigens. These can include viruses, bacteria, and anything else that can cause the immune system to launch an immune response.
Helper T cells
The Lymphatic System.
The lymphatic / immune system and the endocrine system.
The reproductive system interacts with the immune system in several ways to maintain balance and protect reproductive health. During pregnancy, for instance, the immune system undergoes adaptations to tolerate the semi-allogeneic fetus while still defending against pathogens. Hormones produced by the reproductive organs can also influence immune responses, promoting either tolerance or activation depending on the context. Additionally, sexually transmitted infections can trigger immune responses that may affect fertility and reproductive health.
The immune system can be treated through various approaches depending on the condition being addressed. Immunotherapy, such as monoclonal antibodies or vaccines, can enhance or modify immune responses in diseases like cancer or autoimmune disorders. Additionally, immunosuppressive medications may be used to manage overactive immune responses. Lifestyle factors, such as a balanced diet, regular exercise, and adequate sleep, also play a crucial role in maintaining a healthy immune system.
Defensive proteins are manufactured by the immune system. These proteins help protect the body from pathogens such as bacteria and viruses. Examples include antibodies and cytokines.
Cytokines are proteins that act as messengers in the immune system, helping to regulate and coordinate the body's response to infections and other challenges. They can stimulate or suppress immune responses by signaling to different immune cells. This helps to maintain a balanced and effective immune response, preventing overreactions or inadequate responses to threats.
The innate immune system is the branch of the immune system that responds immediately to pathogens. It provides rapid but non-specific defense mechanisms, such as physical barriers and inflammatory responses, against a wide range of invaders.
