Hyperalgesic Effect Evoked by il-16 and its Participation in Inflammatory Hypernociception in Mice.

The systemic administration of interleukin-16 (IL-16, 3-30 ng/kg) induced thermal hyperalgesia in mice, that was prevented by the acute injection of an anti-CD4 antibody (1 µg/kg), the depletion of circulating white blood cells by cyclophosphamide or the specific reduction of circulating CD4 cells provoked by a high dose of an anti-CD4 antibody (30 µg/mouse, 24 h before). IL-16-induced hyperalgesia was locally inhibited after intraplantar (i.pl.

Isolation and Visualization of Plant Stress Granule-Associated Components via On-Beads Digestion and Co-localization Analysis.

Stress granules (SGs) are conserved cytoplasmic biomolecular condensates mainly formed by proteins and RNA molecules assembled by liquid-liquid phase separation. Isolation of SGs components has been a major challenge in the field due to the dynamic and transient nature of stress granule shells. Here, we describe the methodology for the isolation and visualization of SGs proteins from Arabidopsis thaliana plants using a scaffold component as the target.

β-Lactam TRPM8 Antagonists Derived from Phe-Phenylalaninol Conjugates: Structure-Activity Relationships and Antiallodynic Activity.

The protein transient receptor potential melastatin type 8 (TRPM8), a non-selective, calcium (Ca)-permeable ion channel is implicated in several pathological conditions, including neuropathic pain states. In our previous research endeavors, we have identified β-lactam derivatives with high hydrophobic character that exhibit potent and selective TRPM8 antagonist activity. This work describes the synthesis of novel derivatives featuring -terminal amides and diversely substituted '-terminal monobenzyl groups in an attempt to increase the total polar surface area (TPSA) in this family of compounds.
