 Immunological aspects of COVID-19 pathogenesis: a reviewMiló Valdés and Pérez Acevedo Health Leadership and Quality of Life, 2024, vol. 3, .461 Abstract: Introduction: COVID-19, caused by SARS-CoV-2, has challenged the scientific and medical community since its emergence. Understanding the immunopathogenic events that occur during infection is crucial to developing effective treatment and prevention strategies. Objective: To synthesize the immunological aspects in the pathogenesis of coronavirus disease 2019. Development: SARS-CoV-2 infection begins with the entry of the virus into host cells through the ACE2 receptor. Once inside, the virus induces an immune response. In the early stages, the innate immune response is activated, which includes the release of interferons and cytokines. However, in some patients, this response becomes deregulated, triggering a cytokine storm that contributes to systemic inflammation and lung damage. T and B cells also play a crucial role; although the activation of CD8+ T cells can help control the infection, their depletion in severe cases has been associated with worse clinical outcomes. Conclusions: Immunopathogenic events in COVID-19 are complex and can lead to diverse clinical outcomes. Understanding these mechanisms is essential for the development of targeted therapies and effective vaccines. Continued research is critical to improving our response to future pandemics.
