Pain inhibition by opioids-new concepts.

CONCLUSION: The epidemic of opioid misuse has shown that there is a lack of fundamental knowledge about the characteristics and management of chronic pain, that conflicts of interest and validity of models must be more intensively considered in the context of drug development and that novel analgesics with less addictive potential are urgently needed. Currently, the most promising perspectives appear to be augmenting endogenous opioid actions and the selective activation of peripheral opioid receptors.

Sialyl Lewis A (sLeA, also known as CA19-9), a tetrasaccharide selectively and highly expressed on advanced adenocarcinomas including colon, stomach, and pancreatic cancers, has long been considered as an attractive target for active and passive vaccination. While progress in antibodies targeting tumor-associated protein antigens resulted in an impressive array of therapeutics for cancer treatment, similar progress in exploiting tumor-associated carbohydrate antigens, such as sLeA, has been hampered by the lack of a detailed understanding of the singular characteristics of these antigens. We have addressed this issue by an...

Despite recent therapeutic advances, prostate cancer remains a leading cause of cancer-related death. A subset of castration-resistant prostate cancers become androgen receptor (AR) signaling independent and develop neuroendocrine prostate cancer (NEPC) features through lineage plasticity. These NEPC tumors, associated with aggressive disease and poor prognosis, are driven, in part, by aberrant expression of N-Myc, through mechanisms that remain unclear. Integrative analysis of the N-Myc transcriptome, cistrome, and interactome using in vivo, in vitro, and ex vivo models (including patient-derived organoids) identified a l...

In a society where physical activity is limited and food supply is abundant, metabolic diseases are becoming a serious epidemic. Metabolic syndrome (MetS) represents a cluster of metabolically related symptoms such as obesity, hypertension, dyslipidemia, and carbohydrate intolerance, and significantly increases type 2 diabetes mellitus risk. Insulin resistance and hyperinsulinemia are consistent characteristics of MetS, but which of these features is the initiating insult is still widely debated. Regardless, both of these conditions trigger adverse responses from the pancreatic β cell, which is responsible for produci...

Induction of memory CD8+ T cells is important for controlling infections such as malaria and HIV/AIDS and for cancer immunotherapy. Accurate assessment of antigen-specific (Ag-specific) CD8+ T cells is critical for vaccine optimization and for defining correlates of protection. However, conditions for determining Ag-specific CD8+ T cell responses ex vivo using intracellular cytokine staining (ICS) may be variable, especially in humans with complex antigens. Here, we used an attenuated whole parasite malaria vaccine model in humans and various experimental infections in mice to show that the duration of antigenic stimulatio...

This article reviews pharmacological principles and research strategies aiming at novel opioids with reduced side effects. Basic mechanisms underlying pain, opioid analgesia and other opioid actions are outlined. To illustrate the clinical situation and medical needs, plasticity of opioid receptors, intracellular signaling pathways, endogenous and exogenous opioid receptor ligands, central and peripheral sites of analgesic and side effects are discussed. Expert opinion: The epidemic of opioid misuse has taught us that there is a lack of fundamental knowledge about the characteristics and management of chronic pain, that co...

  RX PAD With the death of the entertainer Prince attributed to a fentanyl overdose, and new FDA warnings, opioids have been making headlines. Since the most common reason patients visit the emergency department is for pain, it is not surprising that emergency physicians prescribe and administer medications such as oxycodone on a daily basis. Here are some of the basics about how oxycodone works, and also the reason why chronic users may be at even higher risk of unexpected respiratory depression. HOW IT WORKS: Oxycodone is a semi-synthetic opioid with analgesic properties. Oxycodone binds to mu, kappa, and delta opio...
