Introduction: Forkhead box P3 (Foxp3) is an important regulatory factor for the development and function of T regulatory (Treg) cells. Moreover, it has been established that deficiency of the Foxp3 gene in Treg cells suppresses their regulatory function leading to the development of autoimmune diseases especially autoimmune thyroid diseases. The aim of our study was to estimate the association of three polymorphism of FOXP3 gene with the predisposition to Graves' disease (GD) and Hashimoto's thyroiditis (HT) in children and adolescents.
Materials And Methods: The study was performed in the group consisting of 145 patients with GD (mean age, 16.5 ± 2 years), 87 patients with HT (mean age, 15.2 ± 2.2 years) sequentially recruited from the endocrinology outpatient clinic and 161 healthy volunteers (mean age, 16.3 ± 3 years). DNA was extracted from the peripheral blood leukocytes using a classical salting-out method. The three single nucleotide polymorphisms (SNPs) rs3761549 (-2383C/T), rs3761548 (-3279G/T) and rs3761547 (-3499T/C) in the FOXP3 gene were genotyped by TaqMan SNP genotyping assay using the real-time PCR method. The levels of thyroid hormones, TSH and anti-thyroid autoantibody were determined using chemiluminescence method.
Results: In our study, rs3761549G/A genotype was more frequent in female patients with GD in comparison to healthy female (15% vs. 7%, p = 0.033) with OR = 2.15 and 95% confidence interval for OR: 1.07-4.63. We have also observed rs3761547T/C to be more frequent in females with GD in comparison to control females, and this difference was close to statistically important (13% vs. 7%, p = 0.066) with OR = 1.99 and 95% confidence interval for OR: 0.96-4.48. There were no significant differences in males in analyzed SNPs and in females with rs3761548 SNP.
Conclusion: In conclusion, these results may suggest that rs3761549G/A polymorphism in Foxp3 gene could contribute to GD development in females.

Background: Cancer immunotherapy using immune checkpoint blockade (ICB) has revolutionized cancer treatment. However, patients with multiple myeloma (MM) rarely respond to ICB. Accumulating evidence indicates that the complicated tumor microenvironment (TME) significantly impacts the efficacy of ICB therapy.

Purpose: Bladder preservation therapy in combination with atezolizumab and radiation therapy (BPT-ART) trial, which was a multicenter, open-label, single-arm phase II study, showed a promisingly high interim clinical complete response (cCR) rate of 84.4% (38/45). In the present study, we aimed to identify potential tissue biomarkers for achieving cCR via BPT-ART.

Mitochondrial DNA (mtDNA) is highly polymorphic, and host mtDNA variation has been associated with altered cancer severity. To determine the basis of this mtDNA-cancer association, we analyzed conplastic mice with the C57BL/6J (B6) nucleus but two naturally occurring mtDNA lineages, and , where mitochondria generate more oxidative phosphorylation (OXPHOS)-derived reactive oxygen species (mROS). In a cardiac transplant model, Foxp3+ T regulatory (Treg) cells supported long-term allograft survival, whereas Treg cells failed to suppress host T effector (Teff) cells, leading to acute rejection.

The host immune system is adapted in a variety of ways by tumour microenvironment and growing tumour interacts to promote immune escape. One of these adaptations is manipulating the metabolic processes of cells in the tumour microenvironment. The growing tumour aggressively utilise glucose, its primary energy source available in tumour site, and produce lactate by Warburg effect.

Triple-negative breast cancer (TNBC) is an aggressive subtype that accounts for 10-15 % of breast cancer. Current treatment of high-risk early-stage TNBC includes neoadjuvant chemo-immune therapy. However, the substantial variation in immune response prompts an urgent need for new immune-targeting agents.
