Midbrain dopamine drives splenic immunity through a brain-to-body circuit.

Midbrain dopamine neurons are well-known to shape central nervous system function, yet there is growing evidence for their influence on the peripheral immune systems. Here we demonstrate that midbrain dopamine neurons form a circuit to the spleen via a multisynaptic pathway from the dorsal vagal complex (DVC) through the celiac ganglion. Midbrain dopamine neurons modulate the activity of D1-like and D2-like dopamine receptor-expressing DVC neurons.

Lipopolysaccharide Effects on Neurotransmission: Understanding Implications for Depression.

Immune activation in the body is well studied; however, much less is known about how peripheral inflammation changes brain chemistry. Because depression and inflammation are close comorbidities, investigating how inflammation affects the brain's chemicals will help us to better understand depression. The levels of the monoamines dopamine, serotonin and norepinephrine are thought to be affected by both inflammation and depression.

Immunophenotyping Tracks Motor Progression in Parkinson's Disease Associated with a TH Mutation.

Background: Parkinson's disease (PD) is the second most common neurodegenerative disorder, with genetic factors accounting for about 15% of cases. There is a significant challenge in tracking disease progression and treatment response, crucial for developing new therapies. Traditional methods like imaging, clinical monitoring, and biomarker analysis have not conclusively tracked disease progression or treatment response in PD.

Aurora kinase A inhibition plus Tumor Treating Fields suppress glioma cell proliferation in a cilium-independent manner.

Tumor Treating Fields (TTFields) extend the survival of glioblastoma (GBM) patients by interfering with a broad range of tumor cellular processes. Among these, TTFields disrupt primary cilia stability on GBM cells. Here we asked if concomitant treatment of TTFields with other agents that interfere with GBM ciliogenesis further suppress GBM cell proliferation in vitro.

Immunity on ice: The impact of methamphetamine on peripheral immunity.

Methamphetamine (METH) regulation of the dopamine transporter (DAT) and central nervous system (CNS) dopamine transmission have been extensively studied. However, our understanding of how METH influences neuroimmune communication and innate and adaptive immunity is still developing. Recent studies have shed light on the bidirectional communication between the CNS and the peripheral immune system.
