    Abstract Cystic fibrosis (CF) is a multisystem disorder, but progressive inflammatory lung disease causes the greatest burden of morbidity and death. Recent translational and mechanistic studies of samples from patients, and observations in animal models, indicate that platelets may drive lung injury and contribute to dysregulated host defense in CF lung disease. In this issue of the JCI, Ortiz-Muñoz and Yu et al. explored the role that the cystic fibrosis transmembrane conductance regulator (CFTR) plays in platelet-related inflammation. The authors used mouse and human model systems to show that CFTR dysfunction in platelets increased calcium entry though the transient receptor potential cation channel 6 (TRPC6), causing hyperactivation and consequent experimental lung inflammation. The study persuasively suggests that platelets are critical thromboinflammatory effector cells in CF lung disease. In the context of platelet-related organ injury seen in a variety of other diseases and syndromes, platelets may also contribute to nonpulmonary manifestations and comorbidities of CF.

    Abstract Reports examining lung histopathology in coronavirus disease 2019 (COVID-19) infection provide an essential body of information for clinicians and investigators. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-induced lung injury is complex, involving the airways, alveoli, and pulmonary vessels. Although no anatomic marker is specific, the signature histologic lesion is diffuse alveolar damage (DAD). The biological and molecular mechanisms that drive this pattern of injury are unknown, and the relationship of SARS-CoV-2-induced DAD to physiologic alterations and clinical outcomes in COVID-19-associated acute respiratory distress syndrome is undefined. Additional histologic patterns that may be variant phenotypes have been reported.

    Abstract The need for new coronavirus disease 2019 (COVID-19) therapeutic strategies continues, especially as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants emerge. Zhang and colleagues elegantly engineered a mutant angiotensin-converting enzyme 2 (ACE2) that competitively binds SARS-CoV-2 spike protein, reduces viral uptake by human lung cells, and ameliorates SARS-CoV-2-induced lung injury in mice expressing human ACE2.

    Abstract Platelets are essential cellular effectors of hemostasis and contribute to disease as circulating effectors of pathologic thrombosis. These are their most widely known biologic activities. Nevertheless, recent observations demonstrate that platelets have a much more intricate repertoire beyond these traditional functions and that they are specialized for contributions to vascular barrier integrity, organ repair, antimicrobial host defense, inflammation, and activities across the immune continuum. Paradoxically, on the basis of clinical investigations and animal models of disease, some of these newly discovered activities of platelets appear to contribute to tissue injury. Studies in the last decade indicate unique interactions of platelets and their precursor, the megakaryocyte, in the lung and implicate platelets as essential effectors in experimental acute lung injury and clinical acute respiratory distress syndrome. Additional discoveries derived from evolving work will be required to precisely define the contributions of platelets to complex subphenotypes of acute lung injury and to determine if these remarkable and versatile blood cells are therapeutic targets in acute respiratory distress syndrome.

    Abstract Platelets are essential for physiological hemostasis and are central in pathological thrombosis. These are their traditional and best known activities in health and disease. In addition, however, platelets have specializations that broaden their functional repertoire considerably. These functional capabilities, some of which are recently discovered, include the ability to sense and respond to infectious and immune signals and to act as inflammatory effector cells. Human platelets and platelets from mice and other experimental animals can link the innate and adaptive limbs of the immune system and act across the immune continuum, often also linking immune and hemostatic functions. Traditional and newly recognized facets of the biology of platelets are relevant to defensive, physiological immune responses of the lungs and to inflammatory lung diseases. The emerging view of platelets as blood cells that are much more diverse and versatile than previously thought further predicts that additional features of the biology of platelets and of megakaryocytes, the precursors of platelets, will be discovered and that some of these will also influence pulmonary immune defenses and inflammatory injury.
