HPO iron chelator, CP655, causes the G1/S phase cell cycle block via p21 upregulation.

Iron is known not only for its importance in cellular and metabolic pathways but also for its role in causing cellular toxicities such as production of reactive oxygen species and growth of pathogens. The inability of the human body to physiologically excrete excess iron highlights the need to develop a cheap yet effective iron chelator. This study provides initial evidence of the therapeutic and prophylactic properties of 3-hydroxypyridin-4-one (HPO) chelators in murine collagen-induced arthritis.

Granulocyte-Macrophage Colony Stimulating Factor As an Indirect Mediator of Nociceptor Activation and Pain.

The interaction between the immune system and the nervous system has been at the center of multiple research studies in recent years. Whereas the role played by cytokines as neuronal mediators is no longer contested, the mechanisms by which cytokines modulate pain processing remain to be elucidated. In this study, we have analyzed the involvement of granulocyte-macrophage colony stimulating factor (GM-CSF) in nociceptor activation in male and female mice.

Immune or Genetic-Mediated Disruption of CASPR2 Causes Pain Hypersensitivity Due to Enhanced Primary Afferent Excitability.

Human autoantibodies to contactin-associated protein-like 2 (CASPR2) are often associated with neuropathic pain, and CASPR2 mutations have been linked to autism spectrum disorders, in which sensory dysfunction is increasingly recognized. Human CASPR2 autoantibodies, when injected into mice, were peripherally restricted and resulted in mechanical pain-related hypersensitivity in the absence of neural injury. We therefore investigated the mechanism by which CASPR2 modulates nociceptive function.

Immune Cytokines and Their Receptors in Inflammatory Pain.

There is burgeoning interest in the interaction between the immune and nervous systems. Pain is mediated by primary sensory neurons (nociceptors) that can respond to a variety of thermal, mechanical and chemical signals. Cytokines are now recognized as important mediators of inflammatory pain.

Neurotrophic factors and their inhibitors in chronic pain treatment.

Chronic pain affects more than 20% of the UK population. Neurotrophic factors have been identified as therapeutic targets to improve current treatments of chronic pain. This review article focuses on nerve growth factor (NGF) and interleukin-6 (IL-6) as potential therapeutic targets.

Conference scene: regulatory cells in autoimmunity: analyzing and moderating function.

The 2nd annual conference organized by EuroSciCon was aimed at understanding the various roles played by regulatory cells in autoimmunity. Several eminent researchers from all over Europe presented their novel findings at this conference. The presentations covered a wide range of topics from rheumatoid arthritis to multiple sclerosis to membrane lipids and environmental factors affecting immune responses.
