Oxytocin‐Mediate Modulation of Splenic Immunosuppression in Chronic Social Stress Through Neuroendocrine Pathways

Advanced Science, EarlyView.
Chronic social stress elevates oxytocin levels, leading to immunosuppression by enhancing regulatory T‐cell activity and promoting anti‐inflammatory macrophage polarization in the spleen. Blocking oxytocin signaling reverses these effects but worsens stress‐induced behavioral disorders and reduces survival rates. This highlights oxytocin's dual role in

Short Toxin-like Proteins Attack the Defense Line of Innate Immunity

Toxins, 2013
ClanTox (classifier of animal toxins) was developed for identifying toxin-like candidates from complete proteomes. Searching mammalian proteomes for short toxin-like proteins (coined TOLIPs) revealed a number of overlooked secreted short proteins with an

Capsaicin protects neuromuscular junctions from the inhibitory effects of botulinum neurotoxin A [PDF]

, 2008
Within 24 hrs after injecting botulinum neurotoxin A (BoNT/A) into the hindlimb, mice lost the toe spread reflex and developed progressive muscle weakness. At the same time, the compound muscle action potential amplitude decreased. Injection of capsaicin

Assessment of the direct and indirect effects of MPP+ and dopamine on the human proteasome: implications for Parkinson's disease aetiology [PDF]

, 2008
Mitochondrial impairment, glutathione depletion and oxidative stress have been implicated in the pathogenesis of Parkinson’s disease (PD), linked recently to proteasomal dysfunction.

Smart Organic–Inorganic Copolymer Nanoparticles Distinguish Between Microglia and Cancer Cells for Synergistic Immunotherapy in Glioma

Advanced Science, EarlyView.
The tumor microenvironment‐responsive nanoagonists are developed using an organic–inorganic copolymer composed of the polymer (PC6AB) and manganous phosphate ionic oligomers (MnP). PC6AB with membranolytic activity selectively interacts with tumor cell membranes to induce immunogenic cell death, while MnP activates the STING pathway in immune cells ...

Conflicting Clinical Presentation of Infection with Clostridium botulinum and Clostridium perfringens in a 5-Month-Old Infant

Journal of Pediatrics: Clinical Practice
We present a 5-month-old infant with a 1-day history of poor feeding and sudden progression into generalized weakness including septic shock syndrome after consumption of homemade food. Botulism and sepsis symptoms could be explained by the presence of a

Neurotoxinas de invertebrados como alternativas terapéuticas y herramientas en investigación básica Neurotoxins from invertebrates as alternative therapeutic agents and tools in basic research

Vitae, 2009
Los venenos que producen los animales son una mezcla compleja de proteínas, péptidos, enzimas y trazas de elementos no proteicos tales como carbohidratos y sales, cuya finalidad es inmovilizar la presa y comenzar a digerirla.

Peptide Toxins in Solitary Wasp Venoms

Toxins, 2016
Solitary wasps paralyze insects or spiders with stinging venom and feed the paralyzed preys to their larva. Accordingly, the venoms should contain a variety of constituents acting on nervous systems.

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.
