The aim of this study is to determine the effect of & Gamma;-IR and storage time on the exosomes released from apheresis platelet concentrates (aPC) and to investigate their impact on the maximum platelet aggregation (MPA) and hemostasis. Materials and methods -Eight units of aPC were included in this study. These were divided into four equal portions. Two portions were irradiated before storage while the other two were not. Thus, irradiated and non-irradiated aPC samples for storage Days 0 (D0) and 5 (D5) were obtained. Exosomes were isolated from these samples using a commercial kit and were evaluated to ascertain their parent cells by flow cytometry. For the following steps, exosomes were pooled according to their features. Pooled exosomes were then used for aggregometry and thromboelastography. Results -Platelet-derived exosome (PD-EX) levels decreased in D5 compared to D0 in NI-aPC, whereas granulocyte-derived exosome (GD-EX) levels increased. Exosome pools had no effect on MPA compared to saline groups. Exosome pools decreased the time to initial fibrin formation (R), whereas they increased the rate of clot formation (& alpha;-angle) and coagulation index (CI) compared to saline groups. Discussion -Storage time and & Gamma;-IR each have almost the opposite effects on PD-EX and GD-EX. Exosomes have no impact on MPA, but enhance the clot strength. The impact of exosomes on aPC quality and effectiveness can be ignored or considered as a positive effect.Publication Macrophage polarization capacity of peripheral blood monocytes and monocytic cell line THP-1 in response to secreted factors from COVID-19 patients(Wiley, 2021-08-01) Etgü, Onur; Karaçay, Mehmet; Dombaz, Fatma; Kızmaz, Muhammed Ali; Şimsek, Abdurrahman; Asan, Ali; Yılmaz, Emel; Kazak, Esra; Pınar, İbrahim Ethem; Bal, Salih Haldün; Özkocaman, Vildan; Özkalemkaş, Fahir; Akalın, Emin Halis; Budak, Ferah; Oral, Haluk Barbaros; Ermiş, Diğdem Yöyen; Etgü, Onur; Karaçay, Mehmet; Dombaz, Fatma; Kızmaz, Muhammed Ali; ŞİMŞEK, ABDURRAHMAN; YILMAZ, EMEL; KAZAK, ESRA; PINAR, İBRAHİM ETHEM; BAL, SALİH HALDUN; ÖZKOCAMAN, VİLDAN; ÖZKALEMKAŞ, FAHİR; AKALIN, EMİN HALİS; BUDAK, FERAH; ORAL, HALUK BARBAROS; YÖYEN ERMİŞ, DİĞDEM; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İmmünoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İç Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Temel Tıp Bilimleri Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Enfeksiyon Hastalıkları ve Klinik Mikrobiyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Dr Raşit Durusoy Kan Bankası.; 0000-0001-7288-3250; 0000-0001-5334-7911; 0000-0001-8850-0269; 0000-0002-8856-7356; 0000-0003-1785-3539; 0000-0001-9907-1498; 0000-0001-7530-1279; 0000-0001-7625-9148; 0000-0003-0463-6818; JIJ-1849-2023; JHB-7829-2023; DWR-5356-2022; HKN-2347-2023; AAG-7381-2021; GDP-0005-2022; AAG-8459-2021; JGM-6601-2023; KBR-5535-2024; FQG-8981-2022; JIW-1248-2023; AAU-8952-2020; IZP-9398-2023; K-7285-2012; GYL-2038-2022Publication Investigation of changes in exosomes profile during storage period of erythrocyte suspensions(Springer India, 2020-08-11) Pashazadeh, Mehrdad; Oral, Haluk Barbaros; Budak, Ferah; Pashazadeh, Mehrdad; ORAL, HALUK BARBAROS; BUDAK, FERAH; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Tıbbi İmmünoloji Anabilim Dalı.; 0000-0001-9103-6276; 0000-0001-7625-9148; IZP-9398-2023; F-4657-2014; DZE-7532-2022; FQR-1753-2022This study aimed to investigate the relationship of exosomes in erythrocyte suspension (ES) with leukoreduction and storage period. In this study, we expected to obtain new information about the immunomodulatory effect of allogeneic blood transfusion. Whole blood from healthy donors (10) were transferred to two separate blood bags by an equal amount converted into ES. One of the bags was passed through the leukocyte filter to obtain reduced leukocyte and non-reduced ESs and divided into four equal blood bags. Flow cytometry was used to identify and quantify exosomes in the samples on the 0th, 14th, 28th, and 42nd days at 4 degrees C. The exosomes were first coated with anti-CD9 antibodies with carboxylates beads and exosome volumes were determined by BCA Protein Assay to determine the amount of exosome-containing samples to be bound by beads and investigated by flow cytometry. Exosomes which were derived from Th, NK, NK-T cells were not detected in our study. There were no significant differences in exosome profiles between NL-ES and LR-ES groups. Statistically significant results (in comparison with the 0th day) were found as below. Exosomes that were derived from; T lymphocytes, decrease in LR-ES groups at 42nd-day samples (P < 0.05). Tc lymphocytes, decrease in NL-ES groups at 14th day and 42nd-day samples (P < 0.05). B lymphocytes, a decrease in NL-ES groups at the sample of 28th and 42nd-days (P < 0.05). MDSC and G-MDSC, decrease in both NL-ES groups and LR-ES groups at the sample of 14th, 28th, and 42nd-days (P < 0.05). Our results suggest that exosomes in erythrocyte suspensions are not affected by the leukoreduction procedure. Exosomes which can freely pass from leukocyte filters may be the main cause of the insufficiency of leukoreduction to prevent TRIM.Publication A new protocol for collagen-induced local arthritis model in balb/c mice(Turkish Soc Immunology, 2018-01-01) Güvenç, Gökçen; Karacay, Mehmet; Çiftçi, Kübra; Akkoç, Ahmet; AKKOÇ, AHMET; Oral, Haluk Barbaros; ORAL, HALUK BARBAROS; Yalçın, Murat; YALÇIN, MURAT; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Fizyoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/İmmunoloji Anabilim Dalı.; 0000-0002-1413-3651; 0000-0002-5090-7917; 0000-0003-0463-6818; 0000-0002-5600-8162; AAR-6815-2021; K-7285-2012; AAG-6956-2021Introduction: Numerous models have been described to study the pathogenesis of rheumatoid arthritis, and to develop new therapies; but each of these models has their own limitations. Nowadays, the collagen-induced arthritis (CIA) mouse model is the most commonly used model for rheumatoid arthritis studies in certain mouse strain like DBA/1 mouse. This study aimed to describe a new protocol for local induction of arthritis in Balb/c mice, including the monitoring of clinical arthritis and the protocols for histological examination of paws of mice.Materials and Methods: For the induction of local arthritis in 40 Balb/c mice, they were immunized intra-articularly with type II collagen and subcutaneous complete Freund's adjuvant in 0 day. As the boost immunization, the animals had same injections on day 14. Mice were divided 4 groups, and they were clinically and histopathologically examined for arthritis on 0, 14, 21 and 30 days of arthritis induction.Results: The first signs ol local arthritis appeared in this model 1 week after boost immunization (day 21). The CIA induced paw clinically showed severe erythema and swelling all around the hindquarter on day 21 and 30. The paw reached almost 4 times thicker than the other paws and histopathological examination confirmed the clinical arthritis on day 21 and 30.Conclusion: Using the protocol described, the investigators may reproducibly and economically induce a high incidence of local CIA in Balb/c mice. The described local CLA model may be used to unravel pathophysiological or immunological mechanisms of arthritis, and can also be used to study the effect of new therapeutics.Publication The evaluation of soluble Fas and soluble Fas ligand levels of bronchoalveolar lavage fluid in lung cancer patients(Turkish Assoc Tuberculosis & Thorax, 2005-01-01) Erdoğan, Beril; Uzaslan, Esra; Budak, Ferah; Karadağ, Mehmet; Ediger, Dane; Oral, Barbaros; Goral, Gher; Ege, Ercüment; Gözü, Oktay; Erdoğan, Beril; UZASLAN, AYŞE ESRA; BUDAK, FERAH; KARADAĞ, MEHMET; EDİGER, DANE; ORAL, HALUK BARBAROS; Goral, Gher; Ege, Ercüment; Gözü, Oktay; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Hastalıkları Anabilim Dalı; Uludağ Üniversitesi/Tıp Fakültesi/İmmünoloji Anabilim Dalı; 0000-0001-7625-9148; 0000-0002-9027-1132; 0000-0002-2954-4293; 0000-0003-0463-6818; AAG-8744-2021; AAE-9142-2019; IZP-9398-2023; A-5841-2017; K-7285-2012; F-4657-2014; AAI-1004-2021; ILB-9340-2023; EWU-1122-2022Fas-Fas Ligand (FasL) is one of the major mediator system that activates programmed cell death. Cleavage of membranebound FasL by a metalloproteinase-like enzyme resulted in the formation of soluble FasL (sFasL). sFasL as well as the transmembrane form of FasL binds to Fas and transduces apoptotic signal in Fas-expressing cells. It's suggested that soluble Fas (sFas) and sFasL has an impact on tumor progress and immune escape feature of tumor cells from the host immune system. Since Fas antigen expression in the lungs has been localized to alveolar and bronchial epithelial cells, in this study we aimed to investigate the sFas (pg/mL) and sFasL levels (pg/mL) of bronchoalveolar lavage (BAL) fluid in lung cancer patients. Study population was consisted of 27 patients with lung cancer (mean age 62.9 +/- 10.7 years, 25 control subjects (mean age 47.9 +/- 13.9 years). BAL was performed under local anesthesia, on the unaffected lung of patients; either subsegments of right middle or lingula. BAL sFas and sFasL were evaluated by using ELISA method. The mean levels of sFas was 60.8 +/- 56.8 in lung cancer patient and 39.5 +/- 25.9 in control subjects (p> 0.05). The mean levels of sFasL was 51.6 +/- 39.2 in cancer patient and 41.2 +/- 27.4 in control subjects (p> 0.05). In conclusion, although we did not observe any significant difference between two groups, higher BAL levels of sFas and sFasL levels in lung cancer patients than control subjects, made us thought that apoptosis might have a role development and progression of lung cancer.Publication Il-21: A potential biomarker for diagnosis and predicting prognosis in covid-19 patients(European Respiratory Society Journals, 2021-09-05) Öztürk, Nilüfer Aylin Acet; Ursavaş, Ahmet; Dilektaşlı, Aslı Görek; Demirdöğen, Ezgi; Coşkun, Funda; Ediger, Dane; Uzaslan, Esra; Yöyen-Ermiş, Diğdem; Karaca, Mert; Terzi, Orkun; Bayram, Merve; Ömer, Dilara; Yiğitliler, Büşra; Yurttaş, Ahmet; Maharramov, Shahriyar; Çelik, Gamze; Oral, Barbaros; Karadağ, Mehmet; ACET ÖZTÜRK, NİLÜFER AYLİN; URSAVAŞ, AHMET; GÖREK DİLEKTAŞLI, ASLI; DEMİRDÖĞEN, EZGİ; COŞKUN, NECMİYE FUNDA; EDİGER, DANE; UZASLAN, AYŞE ESRA; YÖYEN ERMİŞ, DİĞDEM; KARACA, MERT; TERZİ, ORKUN ERAY; BAYRAM, MERVE; ÖMER TOPÇU, DİLARA; YURTTAŞ, AHMET; ORAL, HALUK BARBAROS; KARADAĞ, MEHMET; MAHARRAMOV, SHAHRİYAR; YAZICI, GAMZE; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0002-6375-1472; 0000-0002-7400-9089; 0000-0003-3604-8826; 0000-0002-2954-4293; 0000-0001-5871-8769; 0000-0002-9027-1132; AAG-8744-2021; JPK-7012-2023; AAH-3888-2021; AAE-9142-2019; AAI-3169-2021; AAD-1271-2019Publication Evaluation of the roles of regulatory B (Breg) cells and B cell exhaustion in COVID-19(Wiley, 2021-08-01) Budak, Ferah; Çağan, Eren; Kızmaz, Muhammed Ali; Şimşek, Abdurrahman; Dombaz, Fatma; Tezcan, Gülçin; Asan, Ali; Bal, S.
