A “Drug-Dependent” Immune System Can Compromise Protection against Infection: The Relationships between Psychostimulants and HIV

open access: yesViruses, 2021
Psychostimulant use is a major comorbidity in people living with HIV, which was initially explained by them adopting risky behaviors that facilitate HIV transmission.

Metropolis simulations of Met-Enkephalin with solvent-accessible area parameterizations [PDF]

open access: yes, 2003
We investigate the solvent-accessible area method by means of Metropolis simulations of the brain peptide Met-Enkephalin at 300$ K$. For the energy function ECEPP/2 nine atomic solvation parameter (ASP) sets are studied. The simulations are compared with

Great Increase in Antinociceptive Potency of [Leu5]Enkephalin After Peptidase Inhibition

open access: yesJournal of Pharmacological Sciences, 2008
Previous in vitro studies have shown that the degradation of [Leu5]enkephalin during incubation with cerebral membrane preparations is almost completely prevented by a mixture of three peptidase inhibitors: amastatin, captopril, and phosphoramidon.

Effect of met-enkephalin on chromosomal aberrations in the lymphocytes of the peripheral blood of patients with multiple sclerosis

open access: yesBiomolecules & Biomedicine, 2014
Endogenious opiod met-enkephalin throughout previous research manifested cytoprotective and anti-inflammatory effects. Previous research suggests that met-enkephalin has cytogenetic effects.

An Effective and Safe Enkephalin Analog for Antinociception

open access: yesPharmaceutics, 2021
Opioids account for 69,000 overdose deaths per annum worldwide and cause serious side effects. Safer analgesics are urgently needed. The endogenous opioid peptide Leu-Enkephalin (Leu-ENK) is ineffective when introduced peripherally due to poor stability ...

Enkephalin as a Pivotal Player in Neuroadaptations Related to Psychostimulant Addiction

open access: yesFrontiers in Psychiatry, 2018
Enkephalin expression is high in mesocorticolimbic areas associated with psychostimulant-induced behavioral and neurobiological effects, and may also modulate local neurotransmission in this circuit network.

Effects of Long-term antipsychotic treatment on enkephalin-immunoreactive neurons in rats perinatally treated with phencyclidine [PDF]

open access: yesMedicinski Podmladak, 2023
Introduction: Schizophrenia is a chronic mental illness that affects 1% of the world's population. The phencyclidine animal model of schizophrenia is based on the glutamate theory of the development of schizophrenia.

Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera (Insecta: Orthoptera). [PDF]

open access: yesPLoS ONE, 2012
Enkephalins play a major role in reproductive physiology in crustaceans; however their role in reproductive development in insects is largely unknown. We investigated the effect of exposure to exogenous leucine-enkephalin (Leu-Enk), methionine-enkephalin
