BACKGROUND: The combination of autologous mesenchymal stem cells (MSCs) and cardiac stem cells (CSCs) synergistically reduces scar size and improves cardiac function in ischemic cardiomyopathy. Whereas allogeneic (allo-)MSCs are immunoevasive, the capacity of CSCs to similarly elude the immune system remains controversial, potentially limiting the success of allogeneic cell combination therapy (ACCT). OBJECTIVES: This study sought to test the hypothesis that ACCT synergistically promotes cardiac regeneration without provoking immunologic reactions...

Major advances have been made in the treatment of cancer with targeted therapy and immunotherapy; several FDA-approved agents with associated improvement of 1-year survival rates became available for stage IV melanoma patients. Before 2010, the 1-year survival were quite low, at 30%; in 2011, the rise to nearly 50% in the setting of treatment with Ipilimumab, and rise to 70% with BRAF inhibitor monotherapy in 2013 was observed. Even more impressive are 1-year survival rates considering combination strategies with both targeted therapy and immunotherapy, now exceeding 80%...

The cellular degradative pathway of autophagy has a fundamental role in immunity. Here, we review the function of autophagy and autophagy proteins in inflammation. We discuss how the autophagy machinery controls the burden of infectious agents while simultaneously limiting inflammatory pathologies, which often involves processes that are distinct from conventional autophagy. Among the newly emerging processes we describe are LC3-associated phagocytosis and targeting by autophagy proteins, both of which require many of the same proteins that mediate conventional autophagy...

PURPOSE OF REVIEW: The current review aims to provide a current landscape and future trends of biomimetic nanoparticles which have the potential to revolutionize the field of transplantation in the next decade. RECENT FINDINGS: Currently, the inability to safely induce robust donor-specific immunological tolerance makes it difficult to achieve immunosuppression-free graft survival. Despite progresses in the development of nanotherapeutics for antigen-specific immunomodulation in autoimmune diseases and in cancer treatments, few have been proposed and tested in transplantation with success...

Resident memory T cells (TRM) reside in the lung epithelium and mediate protective immunity against respiratory pathogens. Although lung CD8(+) TRM have been extensively characterized, the properties of CD4(+) TRM remain unclear. Here we determined the transcriptional signature of CD4(+) TRM, identified by the expression of CD103, retrieved from human lung resection material. Various tissue homing molecules were specifically upregulated on CD4(+) TRM, whereas expression of tissue egress and lymph node homing molecules were low...

Two pharmacologic approaches that are currently at the forefront of treating advanced cancer are those that center on disrupting critical growth/survival signaling pathways within tumor cells (commonly referred to as "targeted therapies") and those that center on enhancing the capacity of a patient's immune system to mount an antitumor response (immunotherapy). Maximizing responses to both of these approaches requires an understanding of the oncogenic events present in a given patient's tumor and the nature of the tumor-immune microenvironment...

The rise of Zika virus (ZIKV) and its unusual clinical manifestations provided ground for speculative debate. The clinical severity of secondary dengue virus (DENV) infections is associated with antibody-dependent enhancement (ADE), and it was recently suggested that previous exposure to DENV may worsen ZIKV clinical outcomes. In this Opinion article we analyze the relationship among different flaviviruses and ADE. We discuss new evidence obtained in non-human primates and human cohorts demonstrating that there is no correlation to ADE when ZIKV infection occurs in the presence of pre-existing DENV immunity...

Together, malaria and the neglected tropical diseases (NTDs) kill more than 800,000 people annually, while creating long-term disability in millions more. International support for mass drug administration, bed nets, and other preventive measures has resulted in huge public health gains, while support for translational research is leading to the development of some new neglected disease drugs, diagnostics, and vaccines. However, funding for basic science research has not kept up, such that we are missing opportunities to create a more innovative pipeline of control tools for parasitic and related diseases...

Rotator cuff (RC) tendons could beinflicted in many ways with an eventual outcome of pain, weakness and disability, which represent a large burden on health care cost. However, optimal healing, either conservatively or with surgical intervention, remains an issue that needs further investigation. Disorders of the RC tendons may result from external factors like trauma, or internal factors through physiologic and metabolic derangement. Most RC tendon disorders may be asymptomatic and may result from an over-activity of the inflicted shoulder and its tendons...

There are many diseases and biological processes that involve circulating cells in the bloodstream, such as cancer metastasis, immune reaction/inflammation, reproductive medicine, and stem cell therapies. This has driven significant interest in new technologies for the study of circulating cells in small animal research models and clinically. Most currently used methods require drawing and enriching blood samples from the body, but these suffer from a number of limitations. In contrast, "in vivo flow cytometry" (IVFC) refers to set of technologies that allow study of cells directly in the bloodstream of the organism in vivo...

Non-communicable inflammatory skin diseases (ncISD) such as psoriasis or atopic eczema are a major cause of global disease burden. Due to their impact and complexity, ncISD represent a major challenge of modern medicine. Dermatology textbooks describe more than 100 different ncISD based on clinical phenotype and histological architecture. In the last decades, this historical description was complemented by increasing molecular knowledge - and this knowledge is now being translated into specific therapeutics...

Radiotherapy (RT), together with a direct cytolytic effect on tumor tissue, also elicits systemic immunological events, which sometimes result in the regression of distant metastases (abscopal effect). We have shown the safety and anti-tumor activity of a novel metronomic chemotherapy (mCH) regimen with dose-fractioned cisplatin, oral etoposide and bevacizumab, a mAb against the vasculo-endothelial-growth-factor (mPEBev regimen), in metastatic non-small-cell-lung cancer (mNSCLC). This regimen, designed on the results of translational studies, showed immune-modulating effects that could trigger and empower the immunological effects associated with tumor irradiation...

Innate lymphoid cells (ILC) represent a group of lymphocytes that lack specific antigen receptors and are relatively rare as compared to adaptive lymphocytes. ILCs play important roles in allergic and non-allergic inflammatory diseases due to their location at barrier surfaces within the airways, gut and skin and they respond to cytokines produced by activated cells in their local environment. ILCs contribute to the immune response by the release of cytokines and other mediators, forming a link between innate and adaptive immunity...

Phosphatase and tensin homolog deleted on chromosome ten (PTEN) is a well-known tumor suppressor that acts as a dual-specificity phosphatase and is frequently mutated in human cancer. Our previous work has demonstrated that PTEN also plays a vital role in type I interferon responses and antiviral innate immunity. Recently, a translational variant of PTEN with a long N-terminal extension (PTEN-L) has been discovered that is secreted into the extracellular environment and enters recipient cells, where it exerts a phosphatase function antagonistic to PI3K/Akt signaling and tumorigenesis...

ADP-ribosylation is an enzyme-catalyzed post-translational modification of proteins in which the ADP-ribose (ADPR) moiety of NAD+ is transferred to a specific amino acid in a substrate protein. The biological functions of ADP-ribosylation are numerous and diverse, ranging from normal physiology to pathological conditions. Biochemical and cellular studies of the diverse forms and functions of ADPR require immunological reagents that can be used for detection and enrichment. The lack of a complete set of tools that recognize all forms of ADPR [i...

Chronic oxidative stress fuels pathogenesis of a large set of diseases. Oxidative stress is the cause and consequence of numerous diseases including type 1 diabetes mellitus (T1DM), in which there is selective destruction of insulin producing pancreatic β-cells. Studies have documented that hyperglycemia produces profound stress. In vivo production of numerous reactive oxygen, nitrogen, chlorine species and lipid/sugar oxidation products are result of persistent hyperglycemia. Post-translational modifications by reactive species may create new antigenic epitopes and play a role in the development of autoimmune response...
