Keynote: Improving the outcome of T-cell immunotherapy of cancers by pre-conditioning T cell metabolism towards fatty acid catabolism
Time : 09:30-10:15

Abstract:
Recent years have shown tremendous progress in active immunotherapy of cancers through tumor antigen (TA)-specific vaccines, adoptive T cell transfer or check point inhibitors. Nevertheless complete cures remain rare. TA-specific CD8+ T cells rapidly become exhausted once they enter solid tumors. This exhaustion, causing loss of tumor infiltrating CD8+ T cells during tumor progression, is in part cause by metabolic constrains, such as hypoxia and hypoglycemia, within the tumor microenvironment (TME). Lack of glucose forces T cells to switch from glycolysis for energy and biomass production to fatty acid catabolism. Most T cells are apparently unable to adjust their metabolism within the TME and as a consequence loose functions and eventually die. Pre-conditioning T cells during their initial activation in lymphatic tissues or their expansion in vitro towards fatty acid beta oxidation (FAO) preserves their functions and allows them to more effectively reduce tumor burden. CD8+ T cell metabolism can be modified by different types of manipulations such as knockdown of HIF-1a or other key factors of the glycolysis pathway to reduce the cells’ reliance on glucose. FAO can be enhanced directly by strengthening signaling through PPAR-a, the master regulator of lipid metabolism.

Abstract:
Diabetes is a kind of metabolic disease, which causes considerable morbidity in the world. Although pancreas transplantation and islet transplantation has prominent future, we still confront the main difficulty of organ shortage. Thus, a primary and fundamental effective therapy for diabetes is to develop ways to increase beta cell numbers.Here, we reported that under the stimuli of homones, pancreatic duct epithelial cells, also known as pancreatic progenitor cells, could be differented into insulin-secreting islet β-cells.
In this study, we collected pregnant rat serum and added to the culturing medium of isolated rat pancreatic duct epithelial cells. After 7 days of culturing, the pancreatic progenitor cells will be aggregrated (Figure 1). Then we compared the gender difference of the pancreatic progenitor cells, and also the dosage of pregnant serum on the efficiency of differentiation. As observed in Figure 2, all cells treated with pregnant serum experienced expansion (A-D), aggregation (E-H), and islet-like cells formation (I-L) stages. Higher concentration of pregnant serum treated cells (L,J) generate more islet-like cells compared to those of lower ones (I, K). Pancreatic duct epithelial cells isolated from female rats formed larger islet-like sphere compared to those of male ones. However, pancreatic duct epithelial cells cultured with FBS could not form islet-like cells (N, low concentration of FBS control; O, high concentration of FBS control). Then the differented islet-like cells were determined by dithizone staining (P) and aggregated pancreatic duct cells were determined by insulin staining (M). Judged from these two pictures, no matter the aggregrated cells or the sphere-shaped ones are capable of secreting insulin.
In conclusion, the pancreatic progenitor cells could be differented to insulin-secreting islet β-cells by the pregnant serum, which indicats the therapeutic potential of hormone therapy in preventing and/or treating diabetes.

Abstract:
Mechanical endometrial injury prior to IVF has been suggested as a means to increase implantation rates by improving endometrial receptivity. However, the effects of endometrial injury in proliferative vs. luteal phase have not been studied before. This study aimed to explore whether endometrial injury in the proliferative phase of the preceding cycle before in vitro fertilization/embryo transfer (IVF-ET) improves the clinical outcomes in unselected subfertile women compared with injury in luteal phase. In our study, a group of 142 patients were randomized into four groups: injury group (group A: endometrial injury in proliferative phase, n=38; group B: endometrium injury in luteal phase, n=32), and non-injury group as control (group C: non-injury in proliferative phase, n=36; group D: non-injury in luteal phase, n=36). Patients in injury groups underwent endometrial injury in either proliferative phase or luteal phase in the preceding cycle before IVF treatment. Clinical outcomes including implantation, pregnancy, and live birth rates were analyzed among the four groups. As result, the baseline characteristics of the four groups including age, body mass index, duration, type and causes of infertility were similar. There were no significant differences in implantation, clinical pregnancy or live birth rates between injury group and non-injury group. Moreover, there were also no significant differences in implantation, clinical pregnancy, or live birth rates in injury in proliferative phase compared with luteal phase. In conclusions, endometrial injury in the cycle preceding IVF of unselected subfertile women does not increase implantation, clinical pregnancy, or live birth rates. Furthermore, there is no significant difference in clinical outcomes between endometrial injury in the proliferative phase and injury in the luteal phase.

Abstract:
Viral infections are important causes of morbidity and mortality for patients with a hematological malignancy, but the true incidence and consequences of viral infections for these patients who undergo conventional non transplant therapy are inadequately defined. Viral infections in hematological patients may result from reactivation of latent infection or, rarely, from acquisition of a new infection. Thus, screening of patients with hematological malignancies for HHV-6 might be considered mandatory. The aim of this study was to evaluate a possible association between Human Herpesvirus-6 (HHV-6) infection and acute leukemia in adults after receiving chemotherapy treatment for acute leukemia. The patients were divided into two main groups according to the type of leukemia, All patients with newly diagnosed acute leukemia were subjected to history taking, complete clinical examination and routine laboratory investigations. Peripheral blood samples (Whole blood specimens) were collected from all patients for quantitative determination of HHV6 DNA viral load by Taqman probe technique (real time PCR) at day 0 and day 100 of induction chemotherapy after being extracted on day of sampling. Data were fed to the computer and analyzed using IBM SPSS software package version 20.0. (Armonk, NY: IBM Corp). The results argued against an etiological relationship between HHV-6 infection and the genesis of acute leukemia in adults, however, it supports the hypothesis of viral latency and the possibility of virus reactivation in immunocompromised hosts. The possible presence of HHV-6 as an associated or a putative causative agent in leukemia should however be considered.

Abstract:
Hepatocellular carcinoma (HCC) is an expanding health problem with a great impact on morbidity and mortality both in Egypt and worldwide. Recently, metformin and aspirin showed a potential anticancer effect on HCC although their mechanism(s) isn't fully elucidated. To investigate the anti-proliferative effects of combined metformin/ aspirin treatment against HCC, HepG2 cells were exposed to increasing concentrations of metformin, aspirin and combined treatment, and MTT assay was performed. Caspase-3 activity, cell cycle analysis, protein expression of phosphorylated AMP-activated protein kinase (pAMPK) and mammalian target of rapamycin (mTOR) proteins were assessed. Furthermore, the expression and localization of β-catenin protein was assessed by immunocytochemistry (ICC). Finally, protein expression of pAMPK, mTOR and β-catenin was assayed in Egyptian HCC and cirrhotic tissue specimens. Results showed that metformin/aspirin combined treatment had a synergistic effect on cell cycle arrest and apoptosis induction via down-regulation of AMPK activation and mTOR protein expression. Additionally, metformin/aspirin combined treatment enhanced cell-cell membrane localization of β-catenin expression in HepG2 cells, which might inhibit metastatic potential of HepG2 cells. In Egyptian HCC specimens, pAMPK, mTOR and β-catenin proteins showed a significant expression compared to cirrhotic controls. In conclusion, combined metformin/aspirin treatment could be a promising therapeutic strategy for HCC and specifically Egyptian HCC patients.
