BACKGROUND: Neuroinflammation is one of the hallmarks of neurodegenerative diseases, such as Parkinson's disease (PD). Activation of glial cells, including microglia and astrocytes, is a characteristic of the inflammatory response. Glycoprotein non-metastatic melanoma protein B (GPNMB) is a transmembrane glycoprotein that releases a soluble signaling peptide when cleaved by ADAM10 or other extracellular proteases. GPNMB has demonstrated a neuroprotective role in animal models of ALS and ischemia...

Immunotherapy has revolutionized cancer care in the modern era of oncology. Research in immunotherapy has led to important advances in the treatment of melanoma, non-small cell lung cancer and other malignancies using checkpoint inhibition. Multiple systemic immunotherapies have been approved or are currently being investigated for the management of urothelial malignancies (1). Five antibodies targeting the programmed cell death protein 1--programmed cell death 1 ligand 1 (PD-1--PD-L1) pathway have been approved by the U...

Background: Immunotherapies that target immune-checkpoint molecules such PD-1 have helped to achieve durable responses in melanoma treatment. However, 25% of melanoma patients who showed objective responses to PD-1 blockade develop resistance and suffer from disease progression and ultimately death, which necessitates the identification of related resistance mechanisms.IL-34 is a cytokine that controls the biology of myeloid cell lineage through binding to CSF-1R. IL-34 is importantly involved in the pathogenesis of various diseases...

Treatment options for patients with platinum-refractory, recurrent, metastatic head and neck squamous cell carcinoma (HNSCC) are limited, and prognosis is poor. Nivolumab (Opdivo) has been approved by the US Food and Drug Administration (FDA) for the treatment of patients with recurrent or metastatic HNSCC who have disease progression on or after platinum-based therapy. Recently, in patients with metastatic malignant melanoma a significant improvement of outcome and response was achieved with the combination of ipilimumab (CTLA4 antibody) and the programmed death (PD)-1 inhibitor nivolumab compared with monotherapy...

Simultaneous or sequential, planned administration of ipilimumab could significantly enhance the antitumor effects of nivolumab in advanced melanoma patients. On the other hand, the efficacy of ipilimumab for nivolumab-resistant advanced melanoma is extremely poor. Therefore, additional supportive therapy for anti-PD-1 antibody therapy-resistant advanced melanoma has been widely investigated. In this report, we describe a case of multiple in-transit melanomas developing in a nivolumab-resistant patient successfully treated with ipilimumab in combination with imiquimod...

BACKGROUND: While immune checkpoint blockade has greatly improved clinical outcomes in diseases such as melanoma, there remains a need for predictive biomarkers to determine who will likely benefit most from which therapy. To date, most biomarkers of response have been identified in the tumors themselves. Biomarkers that could be assessed from peripheral blood would be even more desirable, because of ease of access and reproducibility of sampling. METHODS: We used mass cytometry (CyTOF) to comprehensively profile peripheral blood of melanoma patients, in order to find predictive biomarkers of response to anti-CTLA-4 or anti-PD-1 therapy...

BACKGROUND: PD-L1 expression in tumour tissues is widely used to select patients to receive anti-PD-1/PD-L1 antibodies, but data are lacking on the correlation of plasma PD-L1 levels with the effect of treatments. METHODS: To investigate the association between PD-L1 mRNA in plasma-derived exosomes and response to nivolumab and pembrolizumab in patients with melanoma (n=18) and NSCLC (n=8), blood was obtained at time point 0 and after 2 months. Exosomal PD-L1 mRNA was measured by digital droplet PCR...

PURPOSE: Cancer immunotherapy has shown promising clinical outcomes in many patients. However, some patients still fail to respond, and new strategies are needed to overcome resistance. The purpose of this study was to identify novel genes and understand the mechanisms that confer resistance to cancer immunotherapy. EXPERIMENTAL DESIGN: To identify genes mediating resistance to T cell killing, we performed an open reading frame (ORF) screen of a kinome library to study whether overexpression of a gene in patient-derived melanoma cells could inhibit their susceptibility to killing by autologous Tumor-Infiltrating Lymphocytes (TILs)...

Background: Anti-PD1/PD-L1 monoclonal antibodies (mAbs) increase overall survival compared to standard of care (SOC) in different tumors. However, a proportion of patients (pts) will have progressive disease (PD) as best response. We conducted a meta-analysis to study the rates of response comparing these antibodies with SOC. Methods: A search of published trials in MEDLINE and EMBASE analyzing anti-PD1/PD-L1mAbs monotherapy compared to SOC. Relative risk (RR) with 95% confidence interval (CI) of response rates between groups was estimated...

An 80-year-old woman with malignant melanoma received 20 cycles of anti-PD-1 antibody (nivolumab) treatment and showed normal glucose tolerance. Three weeks after switching to anti-CTLA-4 antibody (ipilimumab), her plasma glucose level was elevated to 639 mg/dL, her HbA1c was 7.7%, and her fastening serum CPR was undetectable. Anti-GAD and IA-2 antibodies were negative. She was diagnosed with fulminant type 1 diabetes mellitus (F1DM). Remarkably, her anti-insulin antibody was positively converted, and her KL-6 levels increased after ipilimumab therapy...

While cancer immunotherapy provides new exciting treatment options for patients, there is an urgent need for new strategies that can synergize with immune checkpoint blockers and boost the patient response rates. We have developed a personalized vaccine nanodisc platform based on synthetic high-density lipoproteins for co-delivery of immunostimulatory agents and tumor antigens, including tumor-specific neoantigens. Here we examined the route of delivery, safety profiles, and therapeutic efficacy of nanodisc vaccination against established tumors...

Anticancer vaccination is a promising approach to increase the efficacy of cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and programmed death ligand 1 (PD-L1) checkpoint blockade therapies. However, the landmark FDA registration trial for anti-CTLA-4 therapy (ipilimumab) revealed a complete lack of benefit of adding vaccination with gp100 peptide formulated in incomplete Freund's adjuvant (IFA). Here, using a mouse model of melanoma, we found that gp100 vaccination induced gp100-specific effector T cells (Teffs), which dominantly forced trafficking of anti-CTLA-4-induced, non-gp100-specific Teffs away from the tumor, reducing tumor control...

BACKGROUND: Immune-checkpoint inhibitors (ICIs) are novel promising agents for the treatment of malignant tumors. However, critical endocrine immune-related adverse events (irAEs) by ICIs often occur. CASE REPORT: A 63-year-old woman with advanced malignant melanoma had received anti-PD-1 antibody (nivolumab, 2 mg/kg every 3 weeks) for 8 cycles (from day 0 to day 147). On day 168, nivolumab was switched to anti-CTLA-4 antibody (ipilimumab, 3mg/kg every 3 weeks)...

Nivolumab, a monoclonal antibody against the programmed cell death protein 1 (PD-1), has shown promising results in patients with advanced malignancies, including melanoma, lung cancer, and renal cancer. Immune-related adverse events (irAEs) have been reported, including both organ-specific toxicities and skin toxicities. Herein, we report a case of predominantly palmoplantar psoriasis with severe nail involvement, psoriatic arthritis, and autoimmune hypothyroidism after receiving nivolumab treatment for lung cancer...

Both the combination of nivolumab + ipilimumab and single-agent anti-PD-1 immunotherapy have demonstrated survival benefit for patients with advanced melanoma. As the combination has a high rate of serious side effects, further analyses in randomized trials of combination versus anti-PD-1 immunotherapy are needed to understand who benefits most from the combination. Clinical laboratory values that were routinely collected in randomized studies may provide information on the relative benefit of combination immunotherapy...

Learning objectives To evaluate radiation-induced changes in patients with brain metastasis secondary to malignant melanoma who received treatment with Gamma Knife radiosurgery (GKRS) and programmed cell death 1 (PD-1) receptor antagonists. Introduction  Stereotactic radiosurgery and chemotherapeutics are used together for treatment of metastatic melanoma and have been linked to delayed radiation-induced vasculitic leukoencephalopathy (DRIVL). There have been reports of more intense interactions with new immunotherapeutics targeting PD-1 receptors, but their interactions have not been well described and may result in an accelerated response to GKRS...

Since their approval by regulatory agencies worldwide, the anti-PD-1 monoclonal antibodies (mAbs), as monotherapy or in combination with ipilimumab, have become the standard frontline therapy for advanced BRAF-wild-type melanoma and an eminent rival to targeted therapy in the first-line setting for unresectable BRAF-mutated melanoma. Mature survival data from randomized phase 3 trials have emerged, confirming their position in the current treatment schema for advanced melanoma. Recently, the clinical utility of anti-PD-1 agents has extended into other disease settings, such as resected high-risk melanomas, non-cutaneous subtypes, and brain metastases...

BACKGROUND: Uveal melanoma accounts for 85% of the ocular melanomas and has an increased risk of hematogenous spread, most commonly to the liver. After curative intent therapy like surgery and radiation, fifty percent of patients present with distant metastasis. Metastatic uveal melanoma (MUM) does not harbor typically targetable mutations, e.g., BRAF as in cutaneous melanoma. As a result, there is no proven therapy for MUM. Various chemotherapy and immunotherapy regimens have been tried and only partial response (PR) is the best that has been achieved in most of the cases...
