How immune system response!!!!!!!
when virus enter in our human body .The virus has strike protein which can join with the human cell through ACE 2 receptor. Then RNA will be released in the human cell and it formed the assembly through the translation of the protein….. Now there are antigen presenting cells in our body they are known as APCs which can activated T- helper cell then the t helper cell activate and it activate other cells which is B cell and cytotoxic t cell. The B cell form antibodies… It will destroy the infected cell and block the virus meanwhile the cytotoxic t cell identify the infected cell and destroyed in this virus….. In this way the virus vanish from our body.
