Abstract
BACKGROUND Metastatic cholangiocarcinoma (CC), a form of gastrointestinal cancer that originates from the bile ducts, cannot be cured by currently available therapies, and is associated with dismal prognosis. In a previous case report, adoptive transfer of autologous tumor infiltrating lymphocytes (TILs), the majority of which recognized a tumor-specific point mutation, led to a profound and durable cancer regression in a patient with metastatic CC. Thus, more effective treatment for patients with this disease may be developed by using TILs that target cancer-specific mutations, but also other genetic aberrations such as gene fusions. In this context, fusions that involve fibroblast growth factor receptor 2 (FGFR2) and function as oncogenes in a subset of patients with intrahepatic CC (ICC) represent particularly attractive targets for adoptive cell therapy. However, no study to date has explored whether FGFR2 fusions can be recognized by patients' T cells. METHOD To address whether FGFR2 fusions can be recognized by patients' T cells, we tested TILs from four patients with FGFR2 fusion-positive ICC for recognition of peptides and minigenes that represented the breakpoint regions of these fusions, which were unique to each of the four patients. RESULTS We found that CD4+ TILs from one patient specifically recognized the breakpoint region of a unique FGFR2-TDRD1 (tudor domain-containing 1) fusion, and we isolated a T-cell receptor responsible for its recognition. CONCLUSIONS This finding suggests that FGFR2 fusion-reactive TILs can be isolated from some patients with metastatic ICC, and thus provides a rationale for future exploration of T cell-based therapy targeting FGFR2 fusions in patients with cancer. Furthermore, it augments the rationale for extending such efforts to other types of solid tumors hallmarked by oncogenic gene fusions.

Abstract
PURPOSE Immune checkpoint blockade (ICB) agents and adoptive cell transfer (ACT) of tumor-infiltrating lymphocytes (TIL) are prominent immunotherapies used for the treatment of advanced melanoma. Both therapies rely on activation of lymphocytes that target shared tumor antigens or neoantigens. Recent analysis of patients with metastatic melanoma who underwent treatment with TIL ACT at the NCI demonstrated decreased responses in patients previously treated with anti-PD-1 agents. We aimed to find a basis for the difference in response rates between anti-PD-1 naïve and experienced patients. PATIENTS AND METHODS We examined the tumor mutational burden (TMB) of resected tumors and the repertoire of neoantigens targeted by autologous TIL in a cohort of 112 anti-PD-1 naïve and 69 anti-PD-1 experienced patients. RESULTS Anti-PD-1 naïve patients were found to possess tumors with higher TMBs (352.0 vs. 213.5, P = 0.005) and received TIL reactive with more neoantigens (2 vs. 1, P = 0.003) compared with anti-PD-1 experienced patients. Among patients treated with TIL ACT, TMB and number of neoantigens identified were higher in ACT responders than ACT nonresponders in both anti-PD-1 naïve and experienced patients. Among patients with comparable TMBs and predicted neoantigen loads, treatment products administered to anti-PD-1 naïve patients were more likely to contain T cells reactive against neoantigens than treatment products for anti-PD-1 experienced patients (2.5 vs. 1, P = 0.02). CONCLUSIONS These results indicate that decreases in TMB and targeted neoantigens partially account for the difference in response to ACT and that additional factors likely influence responses in these patients.

Abstract
Metal halide perovskites are promising solar energy materials, but their mechanism of action remains poorly understood. It has been conjectured that energetically stabilized states such as those corresponding to polarons, quasiparticles in which the carriers are dressed with phonons, are responsible for their remarkable photophysical properties. Yet, no direct evidence of polarons or other low-energy states have been reported despite extensive efforts. Such states should manifest as below bandgap features in transient absorption and photoluminescence measurements. Here, we use single-particle transient absorption microscopy on MAPbI3 (MA = methylammonium) to unambiguously identify spectrally narrow sub-bandgap states directly; we demonstrate that such signals are completely averaged away in ensemble measurements. Carrier temperature-dependent studies suggest that hot carriers are directed toward transient low-energy states which are immune from permanent defects and traps, thereby giving rise to low carrier recombination rates and ultimately high power conversion efficiency in devices. The utilization of short-lived sub-bandgap states may be a key design principle that propels widespread use of highly heterogeneous materials in optoelectronic applications.

Abstract
Due to an imbalance in the MMP:TIMP ratio determined a tissue damage in arthritis, it is hypothesized that polymorphic variations of the TIMP genes are associated with regulation of the MMP:TIMP balance. To test this hypothesis, the presence of single nucleotide polymorphisms (SNPs) located in the human TIMP-2 and TIMP-4 genes was confirmed in the Korean RA and OA patients. We performed a case-control study comprising 109 unrelated Korean OA patients, 177 unrelated Korean RA patients and 175 healthy subjects. There were statistically significant differences in the genotype distribution and allele frequencies of the C/T polymorphism of TIMP-4 gene between OA and control groups (P = 0.0002 and P = 0.001, respectively). However, no significant association between TIMP-2 polymorphisms and OA was observed. Also, no difference was observed when allele or genotype frequencies of both TIMP-2 and TIMP-4 gene polymorphisms were compared between RA and controls. We demonstrated that the C/T polymorphism which is located on the 3'-untranslational regions of the TIMP-4 gene might be associated with susceptibility to OA patients.

Abstract
In previous reports we have shown that ginsenosides inhibit high threshold voltage-dependent Ca(2+) channels in neuronal cells. However, these studies did not show whether ginsenosides-induced inhibition of Ca(2+) currents discriminates among the various Ca(2+) channel subtypes, although it is known that there are at least five different Ca(2+) channel subtypes in neuronal cells. In this study we investigated the effect of ginsenosides on high threshold voltage-dependent Ca(2+) channel subtypes using their selective Ca(2+) channel blockers nimodipine (L-type), omega-conotoxin GVIA (N-type), or omega-agatoxin IVA (P-type) in bovine chromaffin cells. We could observe that ginsenosides inhibited high threshold voltage-dependent Ca(2+) currents in a dose-dependent manner. The IC(50) was about 120 microgram/ml. Nimodipine had no effect on ginsenosides response. However, the effect of ginsenosides on Ca(2+) currents was reduced by omega-conotoxin GVIA, omega-agatoxin IVA, and mixture of nimodipine, omega-conotoxin GVIA, and omega-agatoxin IVA. These data suggest that ginsenosides are negatively coupled to three types of calcium channels in bovine chromaffin cell, including an omega-conotoxin GVIA-sensitive (N-type) channel, an omega-agatoxin IVA-sensitive (P-type) channel and nimodipine/omega-conotoxin GVIA/omega-agatoxin VIA-resistant (presumptive Q-type) channel. Thus, the selective regulation of voltage-dependent Ca(2+) subtypes by ginsenosides in bovine chromaffin cell could be the cellular basis of antistress effects induced by ginseng.
