Abstract
T cell recognition of human leukocyte antigen (HLA)-presented tumor-associated peptides is central for cancer immune surveillance. Mass spectrometry (MS)-based immunopeptidomics represents the only unbiased method for the direct identification and characterization of naturally presented tumor-associated peptides, a key prerequisite for the development of T cell-based immunotherapies. This study reports on the implementation of ion mobility separation-based time-of-flight (TOFIMS) MS for next-generation immunopeptidomics, enabling high-speed and sensitive detection of HLA-presented peptides. Applying TOFIMS-based immunopeptidomics, a novel extensive benignTOFIMS dataset was generated from 94 primary benign samples of solid tissue and hematological origin, which enabled the expansion of benign reference immunopeptidome databases with > 150,000 HLA-presented peptides, the refinement of previously described tumor antigens, as well as the identification of frequently presented self antigens and not yet described tumor antigens comprising low abundant mutation-derived neoepitopes that might serve as targets for future cancer immunotherapy development.

Abstract
Immunotherapies targeting cancer-specific neoantigens have revolutionized the treatment of cancer patients. Recent evidence suggests that epigenetic therapies synergize with immunotherapies, mediated by the de-repression of endogenous retroviral element (ERV)-encoded promoters, and the initiation of transcription. Here, we use deep RNA sequencing from cancer cell lines treated with DNA methyltransferase inhibitor (DNMTi) and/or Histone deacetylase inhibitor (HDACi), to assemble a de novo transcriptome and identify several thousand ERV-derived, treatment-induced novel polyadenylated transcripts (TINPATs). Using immunopeptidomics, we demonstrate the human leukocyte antigen (HLA) presentation of 45 spectra-validated treatment-induced neopeptides (t-neopeptides) arising from TINPATs. We illustrate the potential of the identified t-neopeptides to elicit a T-cell response to effectively target cancer cells. We further verify the presence of t-neopeptides in AML patient samples after in vivo treatment with the DNMT inhibitor Decitabine. Our findings highlight the potential of ERV-derived neoantigens in epigenetic and immune therapies.

Abstract
T-cell immunity is central for control of COVID-19, particularly in patients incapable of mounting antibody responses. CoVac-1 is a peptide-based T-cell activator composed of SARS-CoV-2 epitopes with documented favorable safety profile and efficacy in terms of SARS-CoV-2-specific T-cell response. We here report a Phase I/II open-label trial (NCT04954469) in 54 patients with congenital or acquired B-cell deficiency receiving one subcutaneous CoVac-1 dose. Immunogenicity in terms of CoVac-1-induced T-cell responses and safety are the primary and secondary endpoints, respectively. No serious or grade 4 CoVac-1-related adverse events have been observed. Expected local granuloma formation has been observed in 94% of study subjects, whereas systemic reactogenicity has been mild or absent. SARS-CoV-2-specific T-cell responses have been induced in 86% of patients and are directed to multiple CoVac-1 peptides, not affected by any current Omicron variants and mediated by multifunctional T-helper 1 CD4+ T cells. CoVac-1-induced T-cell responses have exceeded those directed to the spike protein after mRNA-based vaccination of B-cell deficient patients and immunocompetent COVID-19 convalescents with and without seroconversion. Overall, our data show that CoVac-1 induces broad and potent T-cell responses in patients with B-cell/antibody deficiency with a favorable safety profile, which warrants advancement to pivotal Phase III safety and efficacy evaluation. ClinicalTrials.gov identifier NCT04954469.

Abstract
The DNAJB1-PRKACA fusion transcript is the oncogenic driver in fibrolamellar hepatocellular carcinoma, a lethal disease lacking specific therapies. This study reports on the identification, characterization, and immunotherapeutic application of HLA-presented neoantigens specific for the DNAJB1-PRKACA fusion transcript in fibrolamellar hepatocellular carcinoma. DNAJB1-PRKACA-derived HLA class I and HLA class II ligands induce multifunctional cytotoxic CD8+ and T-helper 1 CD4+ T cells, and their cellular processing and presentation in DNAJB1-PRKACA expressing tumor cells is demonstrated by mass spectrometry-based immunopeptidome analysis. Single-cell RNA sequencing further identifies multiple T cell receptors from DNAJB1-PRKACA-specific T cells. Vaccination of a fibrolamellar hepatocellular carcinoma patient, suffering from recurrent short interval disease relapses, with DNAJB1-PRKACA-derived peptides under continued Poly (ADP-ribose) polymerase inhibitor therapy induces multifunctional CD4+ T cells, with an activated T-helper 1 phenotype and high T cell receptor clonality. Vaccine-induced DNAJB1-PRKACA-specific T cell responses persist over time and, in contrast to various previous treatments, are accompanied by durable relapse free survival of the patient for more than 21 months post vaccination. Our preclinical and clinical findings identify the DNAJB1-PRKACA protein as source for immunogenic neoepitopes and corresponding T cell receptors and provide efficacy in a single-patient study of T cell-based immunotherapy specifically targeting this oncogenic fusion.

Abstract
Abstract
Glioblastoma is known as the most aggressive and most common malignant primary tumor in the central nervous system. Current treatment options comprise maximal surgical resection followed by radiation and/or chemotherapy with temozolomide. However, these therapies are not able to eliminate all tumor cells, which in turn inevitably leads to disease recurrence and an alteration of identified targets in the context of clonal evolution and potential hypermutation. T cell-based immunotherapy holds great promise to target malignant cells with CAR T cell and vaccination strategies, showing first promising results in glioblastoma. These therapies rely on the rejection of cancer cells through recognition of tumor antigens and T cell-mediated cytotoxicity. In previous work, we have characterized such tumor antigens in primary glioblastoma (Neidert et al., Acta Neuropathol, 2018), nonetheless, alterations in relapsed disease have not been addressed thus far. This study investigated the whole exome, transcriptome, and mass-spectrometry-based immunopeptidome of 38 primary and 24 recurrent tumors, including 22 autologous glioblastoma pairs, to determine alterations that occur during glioblastoma progression on multiple comics levels. In concordance with Neftel et al., Cell, 2019, we identified mutations that can be allocated to astrocyte- and mesenchymal-like classified genes. In addition, an increase in the mutation rate in recurrent glioblastoma was observed which is attributed to radiation and chemotherapy pretreatment of tumors. These newly arising tumor-specific mutations give rise to HLA-presented neoepitopes in the primary cohort. Moreover, we identified transcripts that are differentially expressed between the two cohorts, showing a higher expression of transcripts related to immune system responses in the recurrent cohort. Immunopeptidome analysis of the two cohorts revealed high frequent glioblastoma-exclusive HLA class I and class II ligands presented in both the primary and recurrent cohort, serving as universally applicable tumor antigens. Class I and II HLA ligands of each sample were analyzed and revealed 2,146 HLA class I- and 2,753 HLA class II presented antigens that were uniquely identified on primary glioblastoma. A total of 610 and 1,886 source proteins represent recurrence-exclusive antigens presented on HLA class I or II molecules, respectively. Together this work addressed differences in tumor antigen expression and presentation between primary and recurrent glioblastoma using these omics layers to create an overview of the alterations that occur during disease progression. Besides providing a deep insight into the glioblastoma (immuno-)biology during progression, this study yields targets for innovative immunotherapeutic approaches to eliminate residual cells and improve survival in glioblastoma patients.

Abstract
Abstract
Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare tumor disease, which affects children and adolescents without history of primary liver disease. Beside surgical resection established treatment options are lacking for FL-HCC. Recently, the DNAJB1-PRKACA fusion transcript was identified as the oncogenic driver of tumor pathogenesis in 100% of FL-HCC patients. Here, we investigated the role of the DNAJB1-PRKACA fusion protein as a source for immunogenic neoepitopes and showed first immunotherapeutic application of these antigens in a FL-HCC patient.HLA class I- and class II-presented neoantigens derived from the DNAJB1-PRKACA fusion protein were predicted in silico using NetMHCpan 4.1 and SYFPEITHI 1.0, or NetMHCIIpan 4.0, respectively. With this workflow nine binding cores of nine amino acid length for a total of 1290 different HLA class II alleles, as well as 13 HLA class I ligands for the 20 most frequent HLA class I allotypes (European population, iedb.org) were identified. Cellular processing and HLA presentation of DNAJB1-PRKACA-derived peptides was proven by liquid chromatography-coupled tandem mass spectrometry (LC-MS/MS) of DNAJB1-PRKACA-transduced HCC cell lines. Immunogenicity of DNAJB1-PRKACA-derived peptides was assessed for the HLA class II peptide (PII-1) and the HLA-A*24 peptide (PA*24) by in vitro priming experiments which showed an induction of multifunctional peptide-specific CD4+ and CD8+ T cells, respectively, with expression of CD107a, IFNγ, and TNF upon peptide-pulsing. Furthermore, PA*24-specific T cells showed antigen-specific lysis of autologous peptide-loaded target cells and single-cell next-generation sequencing (10x Genomics) of PA*24-specific CD8+ T cells further enabled the identification of DNAJB1-PRKACA-reactive T cell receptors. Based on these preclinical data we applied a peptide vaccine, consisting of three HLA class I ligands (PA*02, PB*44, and PC*05) and PII-1 spanning the DNAJB1-PRKACA fusion region, to a 15-year old patient with histologically confirmed FL-HCC, who experienced multiple tumor relapses after early liver transplant due to unresectable FL-HCC not responsive to chemotherapy. After two vaccinations in vivo induction of multifunctional CD4+ T cells targeting PII-1 and PB*44 was observed by IFNγ ELISPOT. Single-cell RNA sequencing of vaccine-induced CD4+ T cells revealed distinct gene expression clusters of T cell activation and high TCR clonality. DNAJB1-PRKACA-specific T cells persisted in peripheral blood and were accompanied by relapse free survival of the patient until now, more than one year post vaccination. These findings identified the DNAJB1-PRKACA fusion transcript as novel prime source for broadly applicable neoepitopes and corresponding TCRs and provide first evidence for their application in cancer immunotherapy of FL-HCC.

Abstract
O(2) uptake (VO2) kinetics were examined during the follicular (F) and luteal (L) phases of the menstrual cycle to determine if there was an effect of altered sex hormones on the (VO2) response to moderate-intensity exercise. Seven healthy women (age 21 +/- 2 years; mean +/- SD) performed six transitions from 20 W to moderate-intensity exercise (approximately 90% theta L) during the F and L phase. VO2 was measured breath-by-breath and deoxyhemoglobin/myoglobin (Delta HHb) was determined by near infrared spectroscopy. Progesterone and estrogen were significantly (P < 0.05) elevated during the L compared to F phase. VO2 kinetics (tau VO2) were not different in the two phases of the menstrual cycle (F, 22 +/- 5 s; L, 22 +/- 6 s; 95% confidence intervals +/-4 s) nor was the time course of the Delta HHb response (F, TD 11 +/- 2 s, tau 11 +/- 3 s; L, TD 12 +/- 2 s, tau 12 +/- 11 s; tau HHb 95% confidence intervals +/-3 s). Respiratory exchange ratio (RER) was not different between phases for baseline or steady-state exercise and the blood lactate response to exercise was not different. In conclusion, VO2 kinetics at the onset of moderate-intensity exercise are not affected by the phase of the menstrual cycle in young females suggesting either no change in, or no effect of metabolic activation on the on-transient kinetics of moderate-intensity exercise. Additionally, the similar adaptation of Delta HHb in combination with unchanged VO2 suggests that there were no differences in the adaptation of local muscle O(2) delivery.

Abstract
The aim of this study was to identify dosage regimens using intravenous omeprazole and ranitidine that would elevate and consistently maintain intragastric pH > 6 in the first 24 hr of therapy. In 19 healthy, fasting human subjects using continuous 24-hr gastric pH-metry, we studied two dosages of primed infusions of ranitidine (50 mg bolus followed by infusion of either 3 or 6 mg/kg body wt/24 hr) and six regimens of intravenous omeprazole (80-200 mg in 24 hr in two to five boluses). Only the two ranitidine infusions and high doses of omeprazole (> or = 160 mg/day as four or five boluses) raised the intragastric median pH above 5.4. There was no significant difference in the median intragastric pH after high dose ranitidine and high doses of omeprazole. Considerable interindividual variation in intragastric pH was observed after omeprazole therapy. The percentage of intragastric pH > 6.0 during the 24-hr study was lower after omeprazole (35-42%) than after high-dose ranitidine (58%). We conclude that it is possible to raise intragastric pH > 6.0 by use of either primed ranitidine infusion or by repeated boluses of omeprazole. However, maintenance of this high pH in the first 24 hr is difficult with both, more so with omeprazole.
