HUMORAL AND CELL MEDIATED IMMUNO SYSTEM

The point of difference between “humoral and cell-mediated” is that cell-mediated immunity is not able to produce “antigen-specific antibodies” but “humoral immunity” can produce these antigen-specific antibodies.

Introduction

Both the “human immune response” and a “cell-mediated immune response” are very effective in protecting the human body from harmful bacteria and viruses. “Cell-mediated immune response” becomes necessary when harmful effects of bacteria cross limits which are protected by the “Humoral immune response”. In this study, it will be discussed the Importance of the “humoral immune response” and its activities. It will also discuss the importance of cell-mediated immune response to protect the human body from infectious bacteria. A comparison between Humoral and cell-mediated immune responses will be described. 

Main body

Humoral immune response

The humoral immune response is one of the most important arms of the immune system which protects the human body from viruses. It mediates antibody molecules in the human body which helps the human body in protection from viruses. It creates antibodies that protect people from different kinds of external viruses which enter the human body in different human activities. It protects people from different kinds of diseases. The Human immune system is very important for human bodies to protect from viruses and bacteria. This kind of antibody is necessary for any kind of fever or sickness. People must survive in the fiver and sick condition. It protects the human body from many diseases. It creates an antibody in the human body that helps to protect us from the different environmental pollution. It saves people from different kinds of infectious diseases. It has a significant role in building extracellular space in the human body which is very necessary to people’s survival. The humoral immune response has a vital role in protecting extracellular shape in the human body. Antibodies contribute to building immunity in mainly three ways. 

Cell-mediated immune response

The human body can protect the small number of bacteria and viruses that come from external sources with the help of a humoral immune response. But when the power of disease crosses limits protected by the humoral immune system then it is necessary to have a cell-mediated immune system. It builds stronger antibodies in the human body which protect the human body from infectious viruses and bacteria. It is necessary when a pandemic is caused due to the spread of bacteria.  The cell-mediated immune system is mainly associated with the activation of phagocytes, t-lymphocytes, and antigen-specific cytotoxicity. It is necessary when antibodies of the human body are not sufficient to protect against viruses and bacteria that come from external sources. In this case, a tiny amount of protein is extracted from the bacteria that are injected into the human body through the skin. It is injected before or after people are affected by bacteria. It saved many lives during the time of the pandemic. In 24 hours after injection, a red nodule is developed at the site of the injection. The main function of cell-mediated immune response is to remove virus-affected cells from the human body. It is also very effective at defending the human body from the attack of protozoa, fungi, and intracellular bacteria. 

Comparison between humoral and cell-mediated immune response

Comparison on the ground of development of humoral immunity and cell-mediated immunity it has been noted that humoral immunity is developed faster than the cell mediate (Pillet et al. 2018). Thus, through the assessment of the difference between both aspects, it is clearly stated that growth of the humoral cell is quite faster than cell mediate. On the other hand, cell-mediated immunity is active in the case where a cell of the body is being affected by viruses, bacteria and fungus. This statement highlighted that bacteria and tumour cells are targets of “cell-mediated immunity”. Finding differences on the ground of accessory receptors it has been noted that the humoral immunity accessory is “CD40, Ig, CD21, and Fc receptors”. On the other hand, in an analysis of cell mediate accessory receptors it has been noted that accessory receptors of this cell are “CD3, CD2, CD4, CD28, CD8 and integrins”. Based on this it has been that both humoral and cell-mediated accessory receptors have different accessory receptors. This means that in “humoral immunity plasma B cells” release antibodies. 

Conclusion

Based on the whole study it can be concluded that both “humoral immunity” and “cell mediated immunity” have different accessory receptors and different growth rates. On the basis of growth, it can be concluded that the growth of “humoral immunity” is quite faster than “cell mediated immunity”; on the other hand, detailed analysis of cell mediate signifies that the target of this cell immunity is tumour cells and bacteria. If a body cell is being affected by a virus, fungus or bacteria cell-mediated immunity will be activated. Moreover, it can be further concluded that humoral immunity can antigen-specific antibodies which can be possible through cell mediated immunity.
