Difference between innate and adaptive immunity

Adaptive Immunity : it is the immune response against a specific antigen.
Innate Immunity : it is the immediate protective response of the immune system that does not require previous exposure to the antigen.

1. Presented by Muhammad K amil Khan Difference between Innate and adaptive immunity

2. Definition Adaptive Immunity : it is the immune response against a specific antigen . Innate Immunity : it is the immediate protective response of the immune system that does not require previous exposure to the antigen.

3. Specificity Adaptive Immunity : also called specific immunity or acquired immunity because it is against specific antigen or microbes Innate Immunity : Also called non specific or natural immunity because it is activated against every microbes that harm us

4. Type of Defense Adaptive Immunity : Specific immune response is the third line defense of the body . Innate Immunity : Nonspecific immune response can be either first line or second line defense of the body.

5. Correspondence Adaptive Immunity : Specific immune response is the supreme immune response of the body against a particular pathogen . Innate Immunity : Nonspecific immune response is the fundamental immune response of the body against pathogens.

6. Components Adaptive Immunity : Humoral and cell-mediated immunity are the components of the specific immune response . Innate Immunity : Natural flora, physical barriers, chemical barriers, phagocytes, histamine, inflammation, fever, and complement proteins are the components of the nonspecific immune response.

7. Cells Adaptive Immunity : Lymphocytes and antigen-presenting cells are involved in generating a specific immune response . Innate Immunity : Phagocytes such as macrophages, neutrophils, natural killer cells, monocytes, mast cells and dendritic cells are involved in generating a nonspecific immune response.

8. Immunological Memory Adaptive Immunity : They have l0ng term memory because they generates an immunological memory . Innate Immunity : they don’t have memory because they do not generate an immunological memory.

9. Effectiveness Adaptive Immunity : Specific immune response is more effective . Innate Immunity : Nonspecific immune response is less effective than specific immune response.

10. Presence Adaptive Immunity : Developed or created in response to foreign substance Innate immunity : Present at birth

11. Response Adaptive Immunity : slow response (1-2 weeks) Innate immunity : Rapid or quick response

12. Time span Innate immunity : Once activated the immunity have remain throughout the life Adaptive Immunity : It may have long or short life

13. Inheritance Innate immunity : Generally inheritance from parents and passed to offspring Adaptive Immunity : Cannot be inheritance

14. Involvement of complement system Innate immunity : Alternative and lectin pathways Adaptive Immunity : Classical pathway

15. Examples Innate immunity : WBC fight against pathogens and causing redness and swelling when your body exposed or cutted Adaptive Immunity : Due to specific vaccination so that we don’t get c hicken pox, small pox, measles polio virus etc in the whole life
