recommendations! Published in 2020 at "FEBS Letters"

DOI: 10.1002/1873-3468.13910

Abstract: Human embryonic stem cell (hESC)‐derived midbrain dopamine (DA) neurons stand out as a cell source for transplantation with their sustainability and consistency superior to the formerly used fetal tissues. However, multiple studies of DA neurons… read more here.

DOI: 10.1002/glia.24013

Abstract: Our recent finding has demonstrated that astrocytes confer neuroprotection by endogenously producing ciliary neurotrophic factor (CNTF) via transient receptor potential vanilloid 1 (TRPV1) in Parkinson's disease (PD). In this study, the possible molecular target for… read more here.

DOI: 10.1002/mds.29269

Abstract: The accumulation of α‐synuclein (α‐syn) fibrils in intraneuronal inclusions called Lewy bodies and Lewy neurites is a pathological signature of Parkinson's disease (PD). Although several aspects linked to α‐syn–dependent pathology (concerning its spreading, aggregation, and… read more here.

DOI: 10.1007/s00213-025-06747-5

Abstract: Despite decades of research and medical development, relapse to drug seeking continues to be a significant challenge in the treatment of substance use disorders. GABAB receptor (GABAB-R) agonists have been shown preclinically to inhibit relapse… read more here.

DOI: 10.1007/s00429-017-1365-7

Abstract: A growing body of evidence suggests that dopamine plays a role in sleep–wake regulation, but the dopamine-producing brain areas that control sleep–wake states are unclear. In this study, we chemogenetically activated dopamine neurons in the… read more here.

DOI: 10.1016/j.bbrc.2018.07.059

Abstract: Neuropeptides, small peptides found in many mammalian brain, play key roles in communicating with each other to modulate neuronal activity. Here, we reported that endogenous neuropeptide salusin-β has neuroprotective effects on the midbrain dopamine neurons… read more here.

DOI: 10.1016/j.celrep.2017.01.030

Abstract: Circuit-specific signaling of ventral tegmental area (VTA) dopamine neurons drives different aspects of motivated behavior, but the neuromodulatory control of these circuits is unclear. We tested the actions of co-expressed lateral hypothalamic peptides, orexin A… read more here.

DOI: 10.1016/j.celrep.2019.01.014

Abstract: SUMMARY Dorsal raphe (DR) serotonin neurons provide a major input to the ventral tegmental area (VTA). Here, we show that DR serotonin transporter (SERT) neurons establish both asymmetric and symmetric synapses on VTA dopamine neurons,… read more here.

DOI: 10.1016/j.celrep.2021.109975

Abstract: SUMMARY Dopamine (DA) neurons in the ventral tier of the substantia nigra pars compacta (SNc) degenerate prominently in Parkinson’s disease, while those in the dorsal tier are relatively spared. Defining the molecular, functional, and developmental… read more here.

DOI: 10.1016/j.euroneuro.2017.01.015

Abstract: Activation of nicotinic acetylcholine receptors (nAChR) promotes the morphological remodeling of cultured dopamine (DA) neurons, an effect requiring functional DA D3 receptors (D3R). The aim of this study was to investigate the mechanisms mediating D3R-nAChR… read more here.

DOI: 10.1016/j.euroneuro.2019.01.108

Abstract: Phencyclidine (PCP) administration is commonly used to model schizophrenia in laboratory animals. While PCP is well-characterized as an antagonist of glutamate-sensitive N-methyl-D-aspartate (NMDA) receptors, its effects on dopamine signaling are not well understood. Here we… read more here.
