A plethora of immune-related factors sustain a chronic inflammatory state modulated by the metabolic imbalance, the main examples being tumor necrosis factor alpha, interleukin 6, monocyte chemoattractant protein (MCP1), and several adipokines. Among the adipokines leptin (LEP) is steadily increasing interests as it involved in modulating different signaling pathways (e.g., JAK2/STAT3 and MAPK cascade/FOS) and immune cells fate by promoting the switch of memory cells to T helper-1 cell response, increases CD4+CD25- T-cell proliferation, and reduces autophagy during T-cell receptor stimulation. Our work investigates in a pilot study, using protein microarray technology, the LEP circulatory levels in melanoma patients in comparison to other cytokines and chemokines already reported as significantly involved in melanoma initiation and progression.\u0000METHODS: Serum from melanoma cases and pool of serum from healthy volunteers were analyzed by an antibody array platform for a 42-cytokine profile.\u0000RESULTS: The investigation of cytokines, chemokines, and growth factors has shown that all the proinflammatory circulating molecules are elevated in the melanoma patient’s serum. Inflammatory cytokines were found elevated and were correlated to the more advanced stage of the investigated patient (M2). The highest circulatory level was registered for LEP in both melanoma cases; moreover, in M1 patient, although the LEP level was completely comparable with the one found in M2, its IL-1 serum level was normal. In addition, there are ten analytes that show clear abnormal values and in patient M2 high LEP concentration is correlated with high IL-1, MCP-2, MCP-3, MCSF, and TARC serum concentrations.\u0000CONCLUSION: Leptin is pleiotropic adipocytokine involved in various diseases, including skin cancer and melanoma. As it is involved in favoring inflammation and further tumorigenesis, the development of effective leptin-based therapeutic approaches opens new possibilities of adjuvant therapy in skin cancers.","PeriodicalId":377272,"journal":{"name":"South East European Journal of Immunology","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124004979","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}

{"title":"Recruitment of Marrow Donors in the Non-governmental Sector of the Republic of North Macedonia, 2022","authors":"Ana Vučurević, Ivo Spiroski, Emilija Andonoska, Katerina Spiroska, Teodora Fildishevska, M. Spiroski","doi":"10.3889/seejim.2022.6026","DOIUrl":"https://doi.org/10.3889/seejim.2022.6026","url":null,"abstract":"BACKGROUND: Bone marrow transplantation is a well-established lifesaving treatment procedure for many patients with various diseases, such as blood cell cancers (leukemia), some severe hematological diseases (aplastic anemia) and some rare diseases, as well as immune deficiency disorders. Allogeneic hematopoietic stem cell transplantation (HSCT) represents a potentially curative therapy for various hematologic disorders and even the only curative treatment for some diseases (e.g., myelodysplastic syndromes). As an alternative donor strategy, in patients lacking a human leukocyte antigen-matched donor or haploidentical donor, mismatched unrelated donors offer the option of using HSCT in this group of patients. Since the establishment of the first registry in the world for recruitment of unrelated bone marrow donors, the number of newly formed registries has increased over the years. In our country, in addition to the government-funded registry, housed at the Institute of Immunobiology and Human Genetics, Faculty of Medicine in Skopje, an additional non-governmental registry was established, Scientific Foundation SPIROSKI - Marrow Donor Registry (MK-SFSMDR). This will contribute to the increase of the number of newly registered donors in the Republic of North Macedonia and will be a great benefit for the patients searching for a bone marrow transplantation.\u0000AIM: We aimed to present the establishment of the first MDR in the non-governmental sector of the Republic of North Macedonia and the recruitment strategies of new donors.\u0000METHODS: The core activity was the creation, realization, and implementation of the Marrow Donors Recruitment Program. The constructed program for increasing the awareness of the population about HSCT and the importance of becoming a marrow donor encompasses the following activities: (1) creation of a web portal for bone MDR in English, Macedonian, and Albanian language; (2) application of standards from the World Marrow Donor Association for educational material preparation and informed consent creation; (3) composing printed and electronic materials for recruitment activities; (4) organization of public debates for marrow donation in governmental and non-governmental sectors; (5) inclusion of students and other non-governmental organizations for recruitment and registration of marrow donors; and (6) submission the obtained results from Macedonian donors and the donors from other communities (Albanians, Roma, Serbs, Turks, Vlachs, and others) in the database for marrow donors.\u0000RESULTS: In 2022, 988 submissions from marrow donors were registered, from which 678 (68.62%) were females and 310 (31.37%) were males. The biggest number of submissions for marrow donors are in the age group of 26–40 years (567 or 57.38%), followed by the age group of 18–25 (270 or 27.32%) and the age group of 41–55 (151 or 15.28%). The most efficient method for new submissions was through social networks, 538 or 54.45% out of 988 registered donors.

Amniocytes were even more severely affected by nicotine, when nicotine was administered in combination with 900 MHz RF-EMR, due to created synergistic effect. More studies with different settings, exposure times, frequencies, and doses are needed to clarify net effects of exposures to nicotine and RF-EMR radiation, alone or in combination.","PeriodicalId":377272,"journal":{"name":"South East European Journal of Immunology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127315868","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}
