Abstract
We previously evaluated Wilms’ tumor gene 1 (WT1) peptide vaccination in a large number of patients with leukemia or solid tumors and have reported that HLA‐A*24:02 restricted, 9‐mer WT1‐235 peptide (CYTWNQMNL) vaccine induces cellular immune responses and elicits WT1‐235‐specific cytotoxic T lymphocytes (CTLs). However, whether this vaccine induces humoral immune responses to produce WT1 antibody remains unknown. Thus, we measured IgG antibody levels against the WT1‐235 peptide (WT1‐235 IgG antibody) in patients with glioblastoma multiforme (GBM) receiving the WT1 peptide vaccine. The WT1‐235 IgG antibody, which was undetectable before vaccination, became detectable in 30 (50.8%) of a total of 59 patients during 3 months of WT1 peptide vaccination. The dominant WT1‐235 IgG antibody subclass was Th1‐type, IgG1 and IgG3. WT1‐235 IgG antibody production was significantly and positively correlated with both progression‐free survival (PFS) and overall survival (OS). Importantly, the combination of WT1‐235 IgG antibody production and positive delayed type‐hypersensitivity (DTH) to the WT1‐235 peptide was a better prognostic marker for long‐term OS than either parameter alone. These results suggested that WT1‐235 peptide vaccination induces not only WT1‐235‐specific CTLs as previously described but also WT1‐235‐specific humoral immune responses associated with antitumor cellular immune response. Our results indicate that the WT1 IgG antibody against the WT1 peptide may be a useful predictive marker, with better predictive performance in combination with DTH to WT1 peptide, and provide a new insight into the antitumor immune response induction in WT1 peptide vaccine‐treated patients. What's new? The Wilms' tumor gene 1 (WT1) antigen is a promising target for immunotherapeutic strategies against glioblastoma multiforme (GBM), a brain tumor with poor survival rates. The present study shows that vaccination with WT1‐235 peptide can induce WT1‐235‐specific humoral immune responses in GBM patients. WT1‐235 IgG antibody production was significantly associated with prolonged progression‐free survival and overall survival. Survival times were significantly longer in GBM patients with positive delayed‐type hypersensitivity (DTH) responses to WT1 peptide. Thus, in WT1 vaccine‐treated GBM patients, especially those exhibiting positive DTH responses, WT1‐235 IgG antibody production can predict long‐term survival.

Abstract
IntroductionWe have developed a group of school-based universal prevention programs for children's health and adjustment. The programs are characterized by new theories such as the somatic-marker hypothesis and enjoyable methods that utilize animated stories and games. This study adopted one of the programs for the development of self-confidence.ObjectiveThe aim was to examine the effectiveness of the program. In addition to the direct purposes of the program, children's adjustments at school and homeroom class were evaluated as extended effects.MethodsParticipants were third grade children in six public elementary schools in Japan. The final sample included 442 children (219 boys and 223 girls). The program was implemented weekly in one regular 45-minute class over 8 weeks. Participants completed a battery of three questionnaires three times, 1 month before the start of the program (T1), 1 week before the start of the program (T2), and during 1 week after the last class of the program (T3).ResultsResults showed that all of the main endpoints of the program significantly improved in the intervention condition (i.e., changes from T2 to T3), compared to the control condition (i.e., changes from T1 to T2). Moreover, children's adjustment at school and homeroom class increased in the intervention condition, compared to the control condition. However, implicit affect was unchanged.ConclusionThis study suggests that the program is effective for enhancing self-confidence, along with adjustments at school and in class. Future research that examines the sustainability of the effectiveness of the program is planned.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Eukaryotic elongation factor 2 (eEF2) is an essential factor for protein synthesis. Previous studies have shown that the eEF2 gene was overexpressed and plays an oncogenic role in various types of cancers and that eEF2 gene product elicited both humoral immune responses to produce eEF2-specific IgG autoantibody in cancer-bearing individuals and cellular immune responses to induce eEF2 peptide-specific cytotoxic T lymphocytes (CTLs) in vitro. The purpose of the present study was to induce eEF2-specific, antitumor CTL responses in vivo by vaccination with MHC class I-binding eEF2-derived peptide. First, two mouse MHC class I-restricted eEF2‑derived, 9-mer peptides, EF17 (17-25 aa, ANIRNMSVI) and EF180 (180-188 aa, RIVENVNVI) were identified as eEF2-specific CTL peptides, and mice were vaccinated intradermally eight times with either EF17 or EF180 peptide emulsified with Montanide ISA51 adjuvant. Cytotoxicity assay showed that eEF2-specific CTLs were induced in both EF17‑and EF180‑vaccinated mice, and histological study showed no detectable damage in the organs of these mice. Next, to examine in vivo antitumor effects of eEF2 peptide vaccination in a therapeutic model, mice were vaccinated four times with one each of the two eEF2 peptides at weekly intervals after implantation of eEF2-expressing leukemia cells. The vaccination with eEF2 peptides induced eEF2-specific CTLs and suppressed tumor growth, and disease-free survival was significantly longer in EF180-vaccinated mice compared to control mice. The survival was associated with the robustness of eEF2-specific CTL induction. These results indicate that vaccination with MHC class I-binding eEF2 peptide induced eEF2-targeting, antitumor CTL responses in vivo without damage to normal organs, which provided us a rationale for eEF2 peptide-based cancer immunotherapy.

Abstract
Homeostasis requires the immunologically silent clearance of apoptotic cells before they become pro-inflammatory necrotic cells. CD300f (CLM-1) is a phosphatidylserine receptor known to positively regulate efferocytosis by macrophages, and CD300f gene-deficient mice are predisposed to develop a lupus-like disease. Here we show that, in contrast to CD300f function in macrophages, its expression inhibits efferocytosis by DC, and its deficiency leads to enhanced antigen processing and T-cell priming by these DC. The consequences are the expansion of memory T cells and increased ANA levels in aged CD300f-deficient mice, which predispose CD300f-deficient mice to develop an overt autoimmune disease when exposed to an overload of apoptotic cells, or an exacerbated autoimmunity when combined with FcγRIIB deficiency. Thus, our data demonstrates that CD300f helps to maintain immune homeostasis by promoting macrophage clearance of self-antigens, while conversely inhibiting DC uptake and presentation of self-antigens.

Abstract
The impact of mechanical stress on the morphology of crystallographic and magnetic domains in shape-controlled specimens of an orbital-spin-coupled system, MnV2O4, was examined by cryogenic Lorentz microscopy. Because of the difference in thermal expansion coefficients of MnV2O4 and the supporting Mo mesh, compression on the order of 0.01% was applied to the thin-foil specimens near the structural/magnetic phase transformation temperatures. The extent of compression was comparable to the lattice striction associated with the cubic-to-tetragonal phase transformation in MnV2O4 The applied strain thus clearly influenced the morphology of crystallographic domains (i.e. twinning configuration in the tetragonal phase) produced during cooling. The magnetic domain structure was entirely dependent on the configuration of twinning in the tetragonal phase. The observations in this study provided useful information for understanding the relationship between the crystallographic domains and the magnetic domains in MnV2O4.

Abstract
Fas ligand (FasL) triggers apoptosis of Fas-positive cells, and previous reports described FasL-induced cell death of Fas-positive photoreceptors following a retinal detachment. However, as FasL exists in membrane-bound (mFasL) and soluble (sFasL) forms, and is expressed on resident microglia and infiltrating monocyte/macrophages, the current study examined the relative contribution of mFasL and sFasL to photoreceptor cell death after induction of experimental retinal detachment in wild-type, knockout (FasL-/-), and mFasL-only knock-in (ΔCS) mice. Retinal detachment in FasL-/- mice resulted in a significant reduction of photoreceptor cell death. In contrast, ΔCS mice displayed significantly more apoptotic photoreceptor cell death. Photoreceptor loss in ΔCS mice was inhibited by a subretinal injection of recombinant sFasL. Thus, Fas/FasL-triggered cell death accounts for a significant amount of photoreceptor cell loss following the retinal detachment. The function of FasL was dependent upon the form of FasL expressed: mFasL triggered photoreceptor cell death, whereas sFasL protected the retina, indicating that enzyme-mediated cleavage of FasL determines, in part, the extent of vision loss following the retinal detachment. Moreover, it also indicates that treatment with sFasL could significantly reduce photoreceptor cell loss in patients with retinal detachment.
