Specifically, Ehlers-Danlos syndrome is a group of inherited connective tissue disorders that weakens the connective tissue and causes easy bruising. Mast cell activation syndrome (MCAS) is a condition in the connective tissue of vascularized organs that causes recurrent episodes of anaphylactic symptoms. The irregular activation of mast cells may contribute to immunological manifestations in EDS patients. Postural orthostatic tachycardia syndrome (POTS) is an autonomic nervous system disorder characterized by orthostatic intolerance. Review of the literature suggests an overlap of gastrointestinal (GI) symptoms such as nausea and abdominal pain, hernias, perforations, and more. Thus, this paper will delineate each condition's distinct gastrointestinal symptoms and explore similar gastrointestinal relationships among these conditions.","PeriodicalId":40916,"journal":{"name":"AIMS Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70184360","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}

The pathological role of MCs has been demonstrated for a number of highly virulent viral infections. The role of MCs and their Fc receptors for IgE in the immediate-type hypersensitivity reactions and in immunocomplex reactions is well-known, although the role of MCs and their Fc receptors for IgG (FcγR) in immunocomplex processes is much less studied. Antibody-dependent enhancement syndrome (ADE) has been observed in a number of viral infections and is associated with greater secondary infection. ADE is enhanced by virus-specific antibodies, which are not involved in the virus penetration into the cell but are capable of forming immune complexes. The role of MCs in ADE is well-established for dengue infection, RSV infection and coronavirus (CoV) infection. The involvement of IgG-mediated mast cell responses in other human viral infections including Coronavirus disease 2019 (COVID-19) is poorly understood. Recently discovered mast cell activation disease is considered one of the causes of severe post-infectious complications in COVID-19. If the role of MCs in the pathogenesis of severe viral infections, including ADE in recurrent viral infection is clarified, these cells and the products they release may serve as promising targets for such therapeutic agents as histamine receptor blockers or membrane stabilizers to prevent possible complications.","PeriodicalId":40916,"journal":{"name":"AIMS Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70184373","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}

Detailed study of human immune response to SARS-COVIS-2 infection is the important topic for a successful treatment of this disease. Our study was aimed to characterize immune response on the level of antibody profiling in convalescent plasma of patients in Georgia. Antibodies against the following SARS-COV-2 proteins were studied: nucleocapsid and various regions of Spike (S) protein: S1, S2 and Receptor binding domain (RBD). Convalescent plasma of patients 6-8 weeks after initial confirmation of SARS-COV-2 infection were tested. Nearly 80% out of 154 patients studied showed presence of antibodies against nucleocapsid protein. The antibody response to three fragments of S protein was significantly less and varied in the range of 20-30%. Significantly more females as compared to males were producing antibodies against S1 fragment, whereas the difference between genders by the antibodies against nucleocapsid protein and RBD was statistically significant only by one-tailed Fisher exact test. There were no differences between the males and females by antibodies against S2 fragment. Thus, immune response against some viral antigens are stronger in females and we suggest that it could be one of the factors of less female fatality after SARS-COVID-2 infection.","PeriodicalId":40916,"journal":{"name":"AIMS Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41623523","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}

Methods To investigate the factors that are potentially responsible for the different susceptibility of COVID-19 between African-Africans and African-Americans, we collected the data of cumulative confirmed COVID-19 cases and deaths, temperature, humidity, wind speed, age distribution, incidences of age-related diseases, lung diseases, and HIV, and smoking rate in 40 African countries and 50 U.S. states and New York city. Results We found that old age, smoking, and age-related diseases (such as cardiovascular diseases, COPD, diabetes, hypertension, neoplasms, and stroke) were potential risk factors for COVID-19, while chronic kidney disease, tuberculosis, young age, and temperature were potential protective factors.

Some of these therapeutic approaches are aimed at modulating cell functions at genetic level by using miRNA-based and miRNA-targeting treatments. Simultaneously, the crucial role of extracellular vesicles as natural miRNA conveyors is highlighted for induction of antigen-specific immune tolerance, especially that they appear to be easily manipulatable for therapeutic applications. Among other immune-related miRNAs, miR-150 is getting special attention as it is differently expressed by immune cells at various stages of their maturation and differentiation. In addition, miR-150 is involved in different signaling cascades orchestrating humoral and cell-mediated mechanisms of both innate and adaptive immune responses. Therefore, miR-150 is considered a master regulator of immunity in mammals. Currently, physiological miR-150-dependent regulatory circuits and causes of their malfunctioning that underlie the pathogenesis of allergic and autoimmune disorders are being unraveled. Thus, present review summarizes the current knowledge of the role of miR-150 in the pathogenesis and complications of these diseases. Furthermore, the involvement of miR-150 in regulation of immune responses to allergens and self-antigens and in induction of antigen-specific immune tolerance is discussed with the special emphasis on the therapeutic potential of this miRNA.","PeriodicalId":40916,"journal":{"name":"AIMS Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70184185","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}

The resolution of the WH inflammatory phase is characterized by a complex series of events that involves many cellular types, especially neutrophils, macrophages and inflammatory mediators, which are crucial for a correct wound closure. MicroRNAs (miRNAs) play essential roles in wound repair. In fact, miR-142 is linked to inflammation modulating neutrophils' chemotaxis and polarization, while the polarization of M1 toward the M2 phenotype is driven by miR-223 and miR-132 is linked to chemokines and cytokines that activate endothelial cells and attract leukocytes and peripheral cells to the damage site. Thus, understanding the dysregulation of miRNAs in WH will be decisive for the development of new and more effective therapies for the management of chronic wounds.","PeriodicalId":40916,"journal":{"name":"AIMS Allergy and Immunology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70184306","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}

Global data have shown the infection with SARS-CoV-2 to be severe among at least 15% of the infected; the aged and those with premorbid conditions like cancer, cardiovascular, and respiratory diseases. The highest prevalence and mortality are seen in the Americas, with African countries least affected. Severe respiratory distress and multiorgan failure are the usual findings in severe cases. A hyperinflammatory, fulminant, hypercytokinemia that is often further complicated by hypercoagulopathy and multiorgan failure has been reported extensively among severely infected patients. Scientists describe hyper-activated immune response mediated by macrophages secreting copious amounts of interleukin (IL)-6 forming the epicenter of cytokine storm (CS), thereby perpetuating signaling cascade through JAK/Kinase pathway that yields a hypercytokinemia. Researchers globally are exploring JAK/kinase inhibitors, immunomodulatory (immunosuppressive) therapy, cytokines, and cytokine receptor blockers for CS management. In which interestingly some of these agents possess antiviral activity. Here, we reviewed published studies with their respective outcome.
