Background: γδ T cells are a conserved population of natural lymphocytes with a variety of structural and functional heterogeneities, accounting for approximately 0.5% to 10% of total peripheral blood lymphocytes in healthy adults. As a “bridge” between innate and acquired immunity, they have an important role in tumor surveillance. Methods: γδ T cells are considered to be effective anti-tumor effector cells, which can kill tumor cells through direct and indirect methods; γδ T cells can secrete a variety of cytokines, such as tumor necrosis factor α (TNF- α ), γ -interferon (IFN- γ ), perforin, etc., thus, they own the ability to kill tumor cells directly, and can also regulate other innate and adaptive immune cells, and then achieve the purpose of indirectly killing tumor cells, thereby establishing anti-tumor immunity. A unique feature of γδ T cells is that they recognize antigens in a non-major histocompatibility complex (MHC)-restricted manner, and they have strong cytotoxicity to a variety of cancer cells, which make them have important clinical application value. Conclusions: In this review, we provide an overview of the activation mechanisms of γδ T cells and their role in tumor immunity and autoimmune diseases. These studies provide insights into γδ T cell function to facilitate more targeted approaches for tumor therapy.","PeriodicalId":72211,"journal":{"name":"Annals of blood","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48808774","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}

Background: The short shelf life of platelet concentrates (PCs) provokes logistic problems in providing timely PC transfusions during long holiday periods when long or major transportation barriers exists (severe weather, military operations…) or for patients highly alloimmunized by HLA/HPA antibodies. In the European Union the only approved strategy authorized to circumvent the limited storage time of PCs is the cryopreservation using 6% dimethyl sulfoxide (DMSO), at temperature of –80 ℃ or below. Methods: A review of articles referenced in PubMed published in English before 2020 studying the effect of cryopreservation on platelets in vivo and in vitro was performed. Conclusions: Using in vitro techniques available to characterize platelets, significant changes in the structure and function of CPP after thawing are detected. The changes detected suggest that cryopreservation provokes an increase in the procoagulant activity of platelets. However, in vivo studies in healthy volunteers and in patients, have shown the efficacy and safety of the transfusion of CPP in different clinical scenarios. Nevertheless, its current use is limited to situations where liquid stored platelets is not available mainly in military operations, for patients with complex HLA/HPA alloimmunization or for patients with massive bleeding.","PeriodicalId":72211,"journal":{"name":"Annals of blood","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45498284","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}

Globally, surprisingly few pathogens have been implicated in transfusion transmitted infection and most pathogens do not merit specific intervention. Nonetheless, pathogens are emerging much more frequently than is often appreciated, thus necessitating constant vigilance and individual assessment of transfusion-associated risk. Factors that inform the need for intervention include the ramifications (i.e., severity) of infection with a given pathogen, the likelihood of detection in the absence of a defined intervention, tolerance of standard processing and storage conditions (e.g., refrigeration), transfusion transmissibility and clinical penetrance (i.e., development of symptoms following transfusion transmission). Different approaches that have been used to protect the blood supply include donor selection and risk-based deferral, laboratory screening (i.e., using highly sensitive and specific serological and/or molecular assays), bacterial culture (platelets) and pathogen reduction (PR). Each approach has both strengths as well as limitations, whereby strategies are devised to meet national or regional risk, while balancing available resources. TTIs, as a direct reflection of blood transfusion safety, highlight a World divided. In HICs, hypervigilance is increasingly disproportionate to risk; this has contributed to policies and interventions that have been wasteful, incurring enormous cost at marginal—if any—clinical gain. By contrast, many of the routine measures regarded as effective in HICs are conspicuously deficient or even absent in lowand middle-income countries (LMICs) where blood transfusion thus remains a major mode of disease transmission.","PeriodicalId":72211,"journal":{"name":"Annals of blood","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45668289","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}
