Vaccines contain dead or weakened versions of a virus. The body then develops a defense against this virus so that the next time the real virus comes along, the body can identify it and fight it off.
This process of defense development takes place in the immune system of the body. Specialized cells (called b-cells) are created by the bone marrow. These are the cells that produce antibodies. Antibodies work to attack and disable antigens (foreign particles or organisms that have invaded the body, or that the body thinks are invaders). Once the body has developed antibodies for a particular invader, the pattern of those antibodies is stored by the immune system, and duplicates can be readily produced to attack if that invader, or one like it, is detected again. That is what gives you immunity.

Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.
Hematopoietic stem cells are responsible for giving rise to all immune cells, including T cells, B cells, and natural killer cells. These stem cells are found in the bone marrow and have the ability to differentiate into various types of blood cells that make up the immune system.
Following a primary immune response, memory cells are generated from activated B and T cells. These memory cells can recognize the same pathogen if encountered in the future, leading to a faster and stronger secondary immune response. Memory cells are vital for the immune system's ability to provide long-lasting protection against specific pathogens.
The ability of a specific immune cell to proliferate and form many generations of nearly identical cells is called clonal expansion. During clonal expansion, activated immune cells undergo multiple rounds of cell division, resulting in the production of numerous identical daughter cells that can mount a coordinated immune response against the targeted pathogen or antigen.
Testing the lymphoproliferative response of mononuclear cells involves measuring the ability of these immune cells to proliferate in response to nonspecific stimulators like mitogens or antigens. This test is used to evaluate the overall functionality of the immune system and can help assess immune cell function in various conditions, including immunodeficiency disorders and autoimmune diseases. The results can provide insights into the immune system's ability to mount an effective immune response.
Immunity via the production of long lived memory lymphocyte cells in the immune system.
your body has white blood cells which are built up into a immune system these fight the diseases and vaccines boost the system.
Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.
Viruses cannot be destroyed, although doctors can give you vaccines to help fight the virus with your white blood cells in your immune system.
The major histocompatibility complex (MHC) is important in a T cell's ability to recognize antigens presented by antigen-presenting cells. This recognition is crucial for initiating an immune response and coordinating the functions of different immune cells. Deficiencies in MHC expression or function can impact the ability of T cells to mount an effective immune response.
Yes, most of the time the immune system weeds out cells that are abnormal.

IFNs increase the ability of the immune system to recognise cancerous or virally infected cells and their ability to kill these cells by various means. Its important to note that IFNs are an older treatment for CML, these days people use TKIs as they have lower toxicity.

HIV (Human Immunodeficiency Virus) attacks the T cells, which are a type of immune cell that plays a crucial role in coordinating the immune response, including the production of antibodies. By destroying these cells, HIV weakens the immune system's ability to fight infections effectively.
1) Antibodies bind to the pathogen to prevent them from entering or damaging cells 2) Antibodies coat the pathogen stimulating the removal of pathogen by macrophages and other cells 3) They trigger destruction of pathogens by stimulating other immune responses such as complement pathway
