Immunological orchestration and dysregulation in COVID-19 pneumonia: from viral pathogenesis to precision therapeutics in the post-pandemic era.

The COVID-19 pandemic revolutionized our understanding and treatment of pneumonia, particularly highlighting its complex immunological aspects. In this review, we synthesized recent research on COVID-19 clinical management, shedding light on the immune-related landscape of pneumonia in the post-pandemic era. We explored key features of SARS-CoV-2, such as transmission dynamics, emerging variants, and infection mechanisms, before delving into the host immune response following viral exposure. Our discussion emphasized the critical role of immune cells, inflammatory cytokines, and cytokine storms in pneumonia development, alongside immune-mediated lung damage and thrombotic complications. Clinically, we summarized evolving diagnostic methods, treatment approaches, and intensive care protocols, all with a focus on the pivotal role of immunology in pneumonia management. Looking forward, we advocated for a comprehensive approach to addressing ongoing pneumonia challenges, including strengthening epidemic surveillance and advancing immunotherapy research to target abnormal immune responses. Additionally, refining vaccine strategies for durable immunity against evolving viral strains was deemed essential. Overall, this review underscored the central role of immunology in shaping pneumonia management post-COVID-19, aiming to enhance our understanding of disease mechanisms and immunological responses in the post-pandemic era.
