COVID-19 is a highly contagious infectious disease caused by a new coronavirus that can be transmitted from person to person through close contact.  The aim of the present study is to investigate new information in the field of COVID-19 immunology.

The present study uses Google and Google Scholar search engines and articles indexed by reputable international scientific databases including Pub Med, MedLine, and the World Health Organization (WHO). In this study, published articles about COVID-19 and field of immunology were reviewed, and articles that did not have free access (Open Acess) and only access to abstracts were excluded from the study.

In total, studies have been suggested that the amount of cytokines such as IL-10, IL-7, IL-2, G-CSF, and TNF-α has been reported at high levels in patients. The ACE2 receptor is the target receptor for the Covid-19 virus, which binds to it after entering the lungs then IFN-I inhibit the primary replication and inhibition of the virus.

After reviewing the articles, it was found that strengthening the immune system against viral infections is very important. The virus weakens the immune system by disrupting the production of type I interferon and reducing expression in the production of MHC-I, II. One of the best ways to fight COVID-19 is to get the right vaccine to boost immune system and produce T cells and cytokines.

Due to the lack of approved treatment or vaccine against coronavirus, discovering and utilization of natural potentials of the human immunity system is essential in order to combat this virus.

Library studies and international databases including PubMed, Scopus, Google scholar were searched.

The innate immune system, mainly neutrophils and macrophages play a positive role in the initial defense against virus attack, but sustained responses and over expression of inflammatory cytokines and chemokines could lead to the destruction of involved tissues and their loss of function. Acquired immune systems, including T and B lymphocytes by eradicating infected cells, secreting response-boosting cytokines, and producing neutralizing antibodies try to eradicate the infection;however, in many patients this results in exaggeratedTh1 responses, uncontrollable inflammation and tissue damage. Anti-inflammatory, anti-viral, convalescent serum and supportive therapies are currently used for treating the critical patients but none of them show satisfying effects. Molecular and serological diagnostic techniques are rapidly evolving, and several ideas for designing anti-corona vaccines are under preclinical and clinical trials.

Preciseunderstanding of the quality and quantity of immune responses against corona virus and manipulating them in the right direction may be a good solution for COVID-19 problem. Immunology is involved in prevention (vaccine), treatment (anti-inflammatory drugs and enhanced defense) and diagnosis (molecular and serological methods) of COVID-19.
