The aim of current study is to highlight the association between predisposition to multiple sclerosis (MS) and single nucleotide polymorphisms (SNPs) of interleukin-2 (IL2(-330) and IL2(+166)) and transforming growth factorbeta (TGF beta 1(+869) and TGF beta 1(+915)) genes. A total of 68 Iraqi Arab MS patients and 158 age-gender-ethnicity matched healthy subjects were enrolled in this study to determine the genotypes / alleles of IL2(-330), IL2(+166), TGF beta 1(+869) and TGF beta 1(+915) SNPs using sequence-specific primer polymerase chain reaction (SSP-PCR). Significant increased frequencies of GG genotype and G allele of IL2(+166 )SNP was observed in MS patients as compared to controls (77.9% vs. 31.7%, P = .000, OR = 7.6; 85% vs. 60%, P = .00, OR = 3.7, respectively). The frequency of TGF beta 1(+915) SNP GG genotype and G allele were also significantly higher in patients than in controls (72.1% vs. 48.7%, P = .002, OR = 2.7; 85% vs. 70%, P = .001, OR = 2.4, respectively). There was a complete linkage disequilibrium (LD) between - 330 and + 166 SNPs of IL2, whereas LD was absent from TGF beta 1 SNPs in MS patients. Additionally, TG haplotype of IL2(-330, +166 )and CG haplotype of TGF beta 1(+869, +915) showed a significant increased distribution in patients rather than in controls (37.2% vs. 21.8%, P = .000, OR = 2.2; 46.3 vs. 33.1%, P = .008, OR = 1.7, respectively). Consequently, GG genotype / G alleles and TG haplotype of IL2(-330,) (+166) and GG genotype / G alleles and CG haplotype TGF beta 1(+869, +915 )may comprise risk factors for susceptibility to MS in this sample of Iraqi population.

Successful remission in hematological cancers by CAR-T cell immunotherapy has yet to be replicated in solid tumors like GBM. A significant impediment of CAR-T immunotherapy in solid tumors is poor exposure of T cells to tumor antigens resulting in suboptimal CAR-T cell activation, which ultimately fails to induce a robust antitumor immune response. Costimulatory moieties in advanced-generation CARs, along with additional IL2 therapy has been shown to be insufficient to overcome this hurdle and have its cytotoxic limitations. GSK3 is constitutively active in naive T cells and is transiently inactivated during T cell activation resulting in rapid T cell proliferation. Pharmacologic inhibition of GSK3 in GBM-specific CAR-T cells reduced FasL expression, increased T cell proliferation and reduced exhaustion by lowering PD-1 levels resulting in the development of CAR-T effector memory phenotype. Treatment with GSK3-inhibited CAR-T cells resulted in 100% tumor elimination during the tumor-rechallenge experiment in GBM-bearing animals and increased accumulation of memory CART cells in secondary lymphoid organs. These adjuvant-like effects of GSK3 inhibition on activated CAR-T cells may be a valuable adjunct to a successful implementation of CAR-T immunotherapy against GBM and other solid tumors.
