Therefore, we investigate the relationship between the inhibition of c-Kit receptor, AKT, and NF-κB signaling pathways and the regulation of immune escape mechanisms in multiple myeloma. The U266B1 cell line was treated with Masitinib as a c-Kit receptor inhibitor, Perifosine as AKT inhibitor, and Bortezomib as NF-κB inhibitor either in single or combined form. Apoptosis and cell viability were evaluated using flow cytometry and MTT assays, respectively. The relative expression of programmed death-ligand 1 (PD-L1), poliovirus receptor (PVR), and interleukin 6 (IL-6) were determined by real-time PCR. Also, the secretion of IL-6 was measured by ELISA. Our findings demonstrated decreased proliferation of U266B1 cells after co-treatment with Masitinib, Perifosine, and Bortezomib.  An increase in apoptosis was observed in the co-treatment of Masitinib and Perifosine. Furthermore, results elucidated that the expression of PD-L1 and IL-6 decreased after treatment with Masitinib, Perifosine, and Bortezomib in both single and co-treatments. Regarding PVR, combined treatment of U266B1 cells with Masitinib, Perifosine, and Bortezomib decreased the expression level of PVR.

This study, the first of its kind in Iran, aimed to develop a registry system of HLA-typed platelet donors to facilitate the provision of compatible platelets to patients, leveraging the diversity of HLA alleles across Iran's various provinces. This study involved the HLA-typing of 1850 plateletpheresis donors, who were also registered as unrelated stem cell donors, across all blood centers in Iran from 2015 to 2022. HLA-A and HLA-B genotyping was conducted at a low-resolution using polymerase chain reaction-sequence specific primers (PCR-SSP) and real-time PCR. Statistical analysis was performed to determine allelic genotypes and donor profiles. The majority of the donors were male (99.7%), with a mean age of 36 years. The high donor rate in Tehran indicates a larger pool of potential HLA-platelet donors due to a denser population and more donation facilities. The donors were recruited for HLA-compatible plateletpheresis. The frequency of HLA-AB alleles among donors was relatively consistent with those documented by Iranians. Our findings can be utilized to create a foundational HLA database. A registry system for HLA-typed platelet donors is crucial due to high HLA polymorphism and ethnic diversity.

The receiver operating characteristic curve analysis showed that a fold change higher than 2.42 in FGF2 expression indicated asthma.

Elevated IL-8 levels were observed in COVID-19 patients, particularly in ICU patients. MPO-DNA levels, indicating NETosis, were significantly higher in COVID-19 patients and strongly correlated with neutrophil counts (r=0.472).
