TLDR
This review focuses on viral infection of the lung and summarizes recent advances in understanding of the triggering of innate and adaptive immune responses to viral respiratory tract infection, mechanisms of viral clearance, and the well-recognized consequences of acute viral infection complicating underlying lung diseases, such as asthma.Abstract:
Because of its essential role in gas exchange and oxygen delivery, the lung has evolved a variety of strategies to control inflammation and maintain homeostasis. Invasion of the lung by pathogens (and in some instances exposure to certain noninfectious particulates) disrupts this equilibrium and triggers a cascade of events aimed at preventing or limiting colonization (and more importantly infection) by pathogenic microorganisms. In this review we focus on viral infection of the lung and summarize recent advances in our understanding of the triggering of innate and adaptive immune responses to viral respiratory tract infection, mechanisms of viral clearance, and the well-recognized consequences of acute viral infection complicating underlying lung diseases, such as asthma.read more

TL;DR: Recent developments on IL-1 to IL-38, TNF-α, TGF-β, and interferons are reviewed and their cellular sources, targets, receptors, signaling pathways, and roles in immune regulation in patients with allergy and asthma and other inflammatory diseases are discussed.

Toll-Like Receptor 3 Signaling via TRIF Contributes to a Protective Innate Immune Response to Severe Acute Respiratory Syndrome Coronavirus Infection

TL;DR: It is demonstrated that TLR signaling through the TRIF adaptor protein protects mice from lethal SARS-CoV disease, and indicates that a balanced immune response operating through both TRIF-driven and MyD88-driven pathways likely provides the most effective host cell intrinsic antiviral defense responses to severe SARV disease.

TL;DR: It is found that deficiency in signaling via type I interferon receptor led to deregulated activation of group 2 innate lymphoid cells (ILC2 cells) and infection-associated type 2 immunopathology.

TL;DR: In this paper, the authors examined the relationship between immune processes in the respiratory tract and circulation through longitudinal phenotypic, transcriptomic, and cytokine profiling of paired airway and blood samples from patients with severe COVID-19 relative to heathy controls.

DAMPs, PAMPs and alarmins: all we need to know about danger
TL;DR: The term “alarmin” is proposed to categorize such endogenous molecules that signal tissue and cell damage, and can be considered subgroups of a larger set, the damage‐associated molecular patterns (DAMPs).
