Neuronal inflammation is the characteristic pathologic change of acute neurologic impairment and chronic traumatic encephalopathy after traumatic brain injury (TBI). Inhibiting the excessive inflammatory response is essential for improving the neurologic outcome. To clarify the regulatory mechanism of microglial exosomes on neuronal inflammation in TBI, we focused on studying the impact of microglial exosomal miRNAs on injured neurons in this research. We used a repetitive (r)TBI mouse model and harvested the injured brain extracts from the acute to the chronic phase of TBI to treat cultured BV2 microglia in vitro The microglial exosomes were collected for miRNA microarray analysis, which showed that the expression level of miR-124-3p increased most apparently in the miRNAs...

Inflammatory bowel disease (IBD) is an immune-mediated inflammatory condition causing inflammation of gastrointestinal and systemic cells, with an increasing prevalence worldwide. Many factors are known to trigger and maintain inflammation in IBD including the innate and adaptive immune systems, genetics, the gastrointestinal microbiome and several environmental factors. Our knowledge of the involvement of the immune system in the pathophysiology of IBD has advanced rapidly over the last two decades, leading to the development of several immune-targeted treatments with a biological source, known as biologic agents...

Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, is a chronic inflammatory condition of the gastrointestinal (GI) tract. Currently, it is treated with immunosuppressant or biologics that often induce severe adverse effects. Thus, there is an urgent clinical need for more specific treatments. To provide a valid therapeutic tool for IBD therapy, in this work we developed biomimetic nanovesicles by manipulating leukocyte membranes to exploit mechanisms of T-cell recruitment during inflammation...

Cancer immunotherapy relies upon the ability of T cells to infiltrate tumors. The endothelium constitutes a barrier between the tumor and effector T cells, and the ability to manipulate local vascular permeability could be translated into effective immunotherapy. Here, we show that in the context of adoptive T cell therapy, antitumor T cells, delivered at high enough doses, can overcome the endothelial barrier and infiltrate tumors, a process that requires local production of C3, complement activation on tumor endothelium and release of C5a...

   The immune system has come to the forefront of cancer therapeutics in recent years with the success of immune blockade inhibitors in a variety of cancers whose list is increasing with a quick pace. Despite the efficacy of these drugs across a significant part of the cancer spectrum, responses are still seen only in a minority of patients, that implies that most patients are refractory or promptly develop resistance to these agents. Mechanisms of this resistance are important to decipher as this knowledge may lead to the introduction of additional therapies or manipulations to modulate resistance...

Tissue engineering-based therapies targeting cartilage diseases, such as osteoarthritis, require in vitro expansion of articular chondrocytes. A major obstacle for these therapies is the dedifferentiation and loss of phenotype accompanying chondrocyte expansion. Recent studies suggest that manipulation of hedgehog signalling may be used to promote chondrocyte re-differentiation. Hedgehog signalling requires the primary cilium, a microtubule-based signalling compartment, the integrity of which is linked to the cytoskeleton...

Targeted prodrugs exploiting cleavable linkers capable of responding to endogenous stimuli have increasingly been explored for cancer therapy. Successful application of these prodrug designs relies on the manipulation of both stability and responsiveness of the cleavable linkers, which, however, are difficult to be finely regulated, particularly for acid-responsive acylhydrazone bonds. Here we developed a new class of peptide-bridged twin-acylhydrazone linkers (PTA linkers) displaying both an ultrahigh stability and a rapid responsiveness-highly stable in neutral and acidic conditions due to the effect of cooperativity between the two acylhydrazone bonds, easily cleavable in acidic conditions after enzymatically triggered unlocking of the two bonds...

In tumour immunology, complement has traditionally been considered as an adjunctive component that enhances the cytolytic effects of antibody-based immunotherapies, such as rituximab. Remarkably, research in the past decade has uncovered novel molecular mechanisms linking imbalanced complement activation in the tumour microenvironment with inflammation and suppression of antitumour immune responses. These findings have prompted new interest in manipulating the complement system for cancer therapy. This Review summarizes our current understanding of complement-mediated effector functions in the tumour microenvironment, focusing on how complement activation can act as a negative or positive regulator of tumorigenesis...

Stereotactic body radiation therapy (SBRT) stems from the initial developments of intra-cranial stereotactic radiosurgery (SRS). Despite similarity in their names and clinical goals of delivering a sufficiently high tumoricidal dose, maximal sparing of the surrounding normal tissues and a short treatment course, SBRT technologies have transformed from the early days of body frame-based treatments with X-ray verification to primarily image-guided procedures with cone-beam CT or stereoscopic X-ray systems and non-rigid body immo-bilization...

Advanced medical devices, treatments and therapies demand an understanding of the role of interfacial properties on the cellular response. This is particularly important in the emerging fields of cell therapies and tissue regeneration. In this study, we evaluate the role of surface nanotopography on the fate of human dental pulp derived stem cells (hDPSC). These stem cells have attracted interest because of their capacity to differentiate to a range of useful lineages but are relatively easy to isolate. We generated and utilized density gradients of gold nanoparticles which allowed us to examine, on a single substrate, the influence of nanofeature density and size on stem cell behavior...

The immune system protects the body against a wide range of infectious diseases and cancer by leveraging the efficiency of immune cells and lymphoid organs. Over the past decade, immune cell/organ therapies based on the manipulation, infusion, and implantation of autologous or allogeneic immune cells/organs into patients have been widely tested and have made great progress in clinical applications. Despite these advances, therapy with natural immune cells or lymphoid organs is relatively expensive and time-consuming...

Traumatic brain injury (TBI) is a leading cause of morbidity and disability, with a considerable socioeconomic burden. Heterogeneity of pathoanatomical subtypes and diversity in the pathogenesis and extent of injury contribute to differences in the course and outcome of TBI. Following the primary injury, extensive and lasting damage is sustained through a complex cascade of events referred to as "secondary injury." Neuroinflammation is proposed as an important manipulable aspect of secondary injury in animal and human studies...

Electroconvulsive therapy (ECT) is an effective treatment for depression, but can have negative side effects including amnesia. The mechanisms of action underlying both the antidepressant and side effects of ECT are not well understood. An equivalent manipulation that is conducted in experimental animals is electroconvulsive seizure (ECS). Rodent studies have provided valuable insights into potential mechanisms underlying the antidepressant and side effects of ECT. However, relatively few studies have investigated the effects of ECS in animal models with a depression-relevant manipulation such as chronic stress...

Sacroiliac joint (SIJ) dysfunction is a common cause of low back pain in the athlete, especially in sports with repetitive, asymmetric loading. Complex anatomy and broad pain referral pattern make diagnosis difficult. Identifying three or more positive physical examination maneuvers for the SIJ improves examination sensitivity and specificity. Imaging is rarely helpful in establishing the diagnosis but is often used to rule out other pathology. Conservative management with activity modification, medication, physical therapy, manipulation and bracing is first line treatment...
