Researchers at Indiana University Bloomington have developed allosteric modulators of the opioid receptor that were superior to the opioid antidote naloxone at blocking the effects of fentanyl in vitro. They presented their work in a session on “Progress towards more efficacious medicine: Antibiotics and antidotes” at the 2023 spring meeting of the American Chemical Society (ACS).
New research has shed light on a molecular mechanism that fuels inflammation in acute lung injury (ALI), a severe and often fatal condition. Macrophage necroptosis, a form of cell death, is a necessary process contributing to intrapulmonary inflammation during ALI. However, the molecular mechanism that initiates macrophage necroptosis has remained unclear until now.
Tetra Bio-Pharma Inc. has received clearance from Health Canada to proceed with a first-in-human trial in Canada using oral ARDS-003 (onternabez) to treat various immunomodulatory conditions. Oral ARDS-003 is positioned to modulate acute systemic inflammation and prevent sepsis, acute respiratory distress syndrome (ARDS) and organ damage.
Obesity is tied to airway hyperresponsiveness and lung fibrosis, which may lead to patients with asthma and obesity poorly responding to asthma therapy. Blocking proprotein convertase subtilisin/kexin type 9 (PCSK9) is known to reduce serum cholesterol levels and to exert anti-inflammatory effects.
A new study found that nebulized mRNA therapy could be an effective approach to treating acute respiratory distress syndrome (ARDS), a rapidly progressing lung disease that can lead to respiratory failure and death. This work focused on two genes, nuclear factor kappaB (NF-κB) inhibitor α super-repressor (IκBα-SR) and superoxide dismutase 3 (SOD3), previously shown to reduce the severity of pneumonia when delivered prophylactically by viral vectors.
