Conti and colleagues [2] have outlined the binding of COVID-19 to the Toll-like receptor with subsequent cytokine driven fever and pneumonitis, while in Kenderian’s [3] murine model of CRS, ruxolitinib abrogated the development of cytokine excess. Cao [4] reported faster clinical recovery with JAK inhibition and Capochiani’s RESPIRE trial reported an 89% overall response rate (ORR) with ruxolitinib therapy [5]. Discordant findings regarding JAK inhibition have been reported on the superiority of baricitinib plus remdesivir over remdesivir alone in shortening recovery times in hospitalized patients [6] while the randomized RUXCOVID trial failed to impact severe complications of the disease by adding ruxolitinib to standard of care [7]. Other groups [8,9] have reported inflammatory cytokine profiles along with evidence that elevated IL-6 and TNFα are strong predictors of disease severity and survival. While cytokine excess could be an epiphenomenal surrogate for another process, therapeutic strategies have evolved around addressing the excessive cytokine levels complicating a significant fraction of COVID-19 patients.","PeriodicalId":73644,"journal":{"name":"Journal of cellular immunology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46372997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

COVID-19 was declared by the World Health Organization (WHO) as a public health emergency of international concern in January 2020, and then as a pandemic in March 2020. There are over 154.64 million confirmed coronavirus infections and more than 3.23 million deaths reported to the WHO globally until date (as of 11:21 a.m. CEST, 6 May, 2021) [1]. The disease is caused by a zoonotic positive-sense single-stranded ssRNA virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is known to have four structural proteins: spike (S), envelope (E), membrane (M), and nucleocapsid (N), with close genetic similarity to bat coronaviruses.

One of the reasons can be attributed to the lack of knowledge about the duration of infectivity at the beginning of the pandemic, resulting in hospital isolation of patients and absence periods of employees. In particular, the absence of healthcare workers placed an unprecedented strain on healthcare systems. Thereupon, at least one negative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test from a respiratory specimen was required for ending isolation [1]. However, prolonged SARS-CoV-2 RNA shedding was reported for several weeks following infection [2-9].

An increasing body of evidence has shown the promising results with respect to transient recovery of cardiac function in a variety of animal models with the use of stem cells interventions.

Moreover, the optimal cell population for organ regeneration has not been yet identified. Prior to possible optimization strategy to find ideal cell candidates, we shall keep in mind that successful organ regeneration is a very complex process. Within such development, the administered cells require proper homing and a graft retention that would be next followed by the cell electromechanical coupling with recipient organ cardiomyocytes [1]. Recent advances in molecular imaging techniques opened many platforms that would allow tracking of transplanted cells and optimization of delivery protocols with their subsequent multimodal imaging [2].","PeriodicalId":73644,"journal":{"name":"Journal of cellular immunology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49397988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concurrently, ensuing myocardial tissue death and necrosis results in the release of danger associated molecular patterns (DAMPs), cytokines, chemokines, bioactive lipids, as well as activation of the complement cascade [1-3]. Collectively, these events direct a pronounced and immediate immune response, which includes the recruitment of peripheral blood leukocytes to the site of injury [2,3]. These infiltrating neutrophils are primarily responsible for the clearance of necrotic tissue and cellular debris in ischemic regions via their release of a host of proteolytic enzymes/proteases. While this constitutes a necessary early step in the myocardial repair process at the site of injury, neutrophil-derived reactive oxygen species (ROS) and pro-inflammatory cytokines/chemokines can contribute to collateral damage of surviving myocardium and amplify tissue injury [3,4]. Nevertheless, neutrophils are imperative for proper infarct healing as their depletion prior to MI leads to a dysregulated immune response, excessive scarring, and impaired ventricular function [5]. Within days of an MI, neutrophils undergo cell death and disappear from infarcted tissue [3,4]. Recruitment of neutrophils is followed by two waves of monocyte infiltration. First, early recruitment of Ly6CHigh monocytes expressing pro-inflammatory cytokines, and second, infiltration of Ly6CLow monocytes with pro-resolving and pro-reparative function [3,6,7]. Ly6CHigh monocyte migration is driven by the presence of tissue CCL2 chemokine gradients and their interaction with their cognate receptor, CCR2 [8]—a group of monocytes that are principally sourced from bone marrow and spleen. Subsequently, these monocytes differentiate into Ly6CLowCCR2High macrophages, known as monocyte-derived macrophages [9,10]. These are distinct from Ly6CLowCCR2Low macrophages deposited in the myocardial tissue during embryonic development [11-13]. Both macrophage populations (Ly6CLowCCR2High and Ly6CLowCCR2Low) contribute to myocardial repair by clearance of dead tissue via efferocytosis and production of pro-reparative and pro-resolving mediators. Macrophagederived cytokines play an essential role in the proliferation and activation of cardiac fibroblasts (fibroblast-myofibroblast conversion) that deposit collagen at the site of injury. This process of scar formation fulfills the immediate need to preserve the structural integrity","PeriodicalId":73644,"journal":{"name":"Journal of cellular immunology","volume":"3 2","pages":"85-90"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8098722/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38889821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such modality of care includes telehealth services, which have experienced a rapid rise in utility with a reported 4,347% increase in telehealth visits from March 2019 to March 2020 [1]. Although used for decades, telemedicine has historically been limited by reimbursement, as well as systems adoption and maintenance costs. Physical distancing measures throughout the pandemic, however, necessitated essentially overnight adoption of insurance coverage in both public and private sectors. Dermatology is among the earliest and most well-suited specialties to adopt telemedicine given the visual nature of the specialty [2]. Since the onset of the COVID-19 pandemic, we have seen a radical uptake of teledermatology services across the nation.
