An innate immune cell is responsible for expressing the encoded receptors, which are referred to as Toll-like receptors, which have the capability of recognizing general danger as well as patterns associated with pathogens. These receptors are capable of recognizing bacteria, fungi, viruses, and several other noninfectious problems. However, they do not have the capability of distinguishing between certain strains of viruses and bacteria. Different kinds of innate immune cells have different functions. They normally include:
• Mast cells
• Dendritic cells
The main feature associated with all these cells is responding broadly as well as quickly when any situation arises and leads to inflammation. Innate immune cells are also capable of activating adaptive immunity. Innate cells are important for host defense. If there is any disorder in the function of the innate cell, it can be responsible for infections.
The adaptive immune cells are specialized with adaptive T or B cells. These cell receptors are capable of recognizing certain signals as opposed to general patterns. Each receptor is capable of recognizing antigen, which is a molecule that is going to bind to TCR or BCR. Antigens are normally processed by the innate immune cells and then they are presented to the adaptive cells, within the lymph nodes, as stated by www.niaid.nih.gov.
Immune memory is one of the most important features associated with the adaptive immune response. After the T or B cells have been activated, they are capable of expanding rapidly. When the problems start resolving, the cells will stop dividing and will be returned within your body as crucial memory cells. Whenever a similar pathogen is entering your body, the memory cell will be ready to react and clear the pathogen even before it is capable of establishing itself.
Immunization or vaccination is one of the best ways of training the immune system against particular pathogens. Vaccination is capable of achieving immune memory without any infection, and hence your body becomes prepared to fight against any bacteria or virus that enters your body. A great vaccine will be capable of activating both your innate as well as adaptive immunogenic response. Immunogens are used for activating adaptive immune responses to generate certain important memory cells. The goal of any vaccine design is selecting immunogens, which will help in selecting a response against particular pathogens.
It is crucial to understand the features that are associated with the immune response so that you can understand how your body is dealing with the different pathogens that are entering your body. Consider everything that has been mentioned above so that you get the perfect idea regarding the features associated with immune response.
