Adaptive immune response acts by recognition of the pathogen and retained after the pathogenic infection has been eliminated (Doan, 2008).
The Humoral immune response is a branch of adaptive immune response. Humoral immune response act on pathogens that are outside the bed such as toxins and bacterias, during the response antibodies which are protein bodies present in the body are produced and secreted into the blood stream and other body fluids to help in fighting with the intruding agents by binding to them and destroying them (Doan, 2008).
In the case of the student who was first exposed to the avian flu the humoral system retained the response given first hence when the student was infected again by the flu the immune response had the memory and hence acted on it faster than the first time (Doan, 2008).
The T helper cells are responsible for suppressing and regulation of the innate responses. Low helper T cells results in hypersensitivity reactions to the patient because the body will view the host’s antigen presenting the antibody as foreign and go on to destroy all the host antigens.
They include chemical, mechanical, and biological barriers. Chemically the skin produces an antimicrobial agent that protects against pathogens. Mechanically, sneezing helps to expel foreign bodies present in the respiratory tract.
This response comes first after an infection. Cytokines are produced and they communicate with the white blood cells to recruit immune cells to the infection site hence healing takes place after removal of the pathogens (Doan, ...Download file to see next pagesRead More

The antigens produced by human body itself are called self-antigens. However, thymus is capable of distinguishing between external and self-antigens through various mechanisms. Body’s response to self-antigens can trigger auto-immune disorders. Therefore, it develops tolerance towards self-antigens.

The immune response
Upon interaction with a pathogen in the body these T cells produce a specific response. T cells can only be activated if they their receptors recognize the pathogen entering the body. The pathogens are recognized by the T cells with the help of the Antigen Presenting Cells (dendritic cells, macrophages etc).
