Serotonin attenuates tumor-necrosis-factor-alpha-induced intestinal inflammation by interacting with human mucosal tissue

Project description:The intestine houses the largest immune system and is serviced by the largest and most complex peripheral nervous system in the human body. The gut-brain axis orchestrates communication between the central and enteric nervous systems, playing a pivotal role in regulating overall body function and intestinal homeostasis. Using a human 3D in vitro model, we investigated the effect of serotonin, a neuromodulator produced in the gut, on immune cell and intestinal tissue interactions. Our findings revealed that serotonin attenuates the tumor-necrosis-factor-alpha-induced pro-inflammatory response, mostly by affecting the expression of chemokines. Serotonin was found to impact tissue-migrating monocytes’ phenotype and distribution, without direct contact with the cells, by remodeling the intestinal tissue. Collectively, using fully human model of intestine, our results show that serotonin has a crucial role in communication among gut-brain axis components and regulates monocyte migration and plasticity, thereby contributing to gut homeostasis and the progression of intestinal inflammation. In vivo studies focused on role of neuromodulators in gut homeostasis and inflammation have shown controversial results, highlighting importance of development of human experimental models. Moreover, our results emphasize importance of human health research in human-cell-based models and suggests serotonin signaling pathway as new therapeutic target for inflammatory bowel disease.

The gut‒brain axis orchestrates communication between the central and enteric nervous systems, playing a pivotal role in regulating overall body function and intestinal homeostasis.

Serotonin attenuated the tumor necrosis factor-induced proinflammatory response, mostly by affecting the expression of chemokines. Serotonin affected the phenotype and distribution of tissue-migrating monocytes, without direct contact with the cells, by remodeling the intestinal tissue.

Hyperactive Mouse Serotonin Transporter Interacting Proteins LC-MSMS

Project description:The serotonin (5-HT) transporter (SERT) is a key determinant of the concentration of 5-HT available for synaptic signaling and is the target of the antidepressant-selective 5-HT reuptake inhibitors (SSRIs). In addition to the role of SERT in mediating the actions of antidepressant medications, multiple, rare gain of function coding variants in SERT have been identified in subjects with autism spectrum disorder (ASD). The Blakely lab has extensively characterized the structural and functional impact of one of these variants, SERT Ala56, in vitro and in vivo, revealing a constitutively-imposed, biased conformation that enhances transporter function and that perturbs transporter regulation. We hypothesize that SERT Ala56 disrupts the interactions of molecular networks that normally ensure proper transporter structure, localization and regulation, and whose elucidation may reveal new determinants of serotonergic dysfunction in ASD. Here, we pursue an unbiased proteomic analysis of changes in SERT interacting protein (SIPs) imposed by the SERT Ala56 variant, expressed in transgenic mice. Further investigation of the SIPs and associated networks nominated through our studies may provide new opportunities to detect and modulate brain networks that contribute to the underlying complexity of ASD.

Serotonin 2A Receptor Attenuates Psoriatic Inflammation by Suppressing IL-23 Secretion in Monocyte-derived Langerhans cells

Project description:Serotonin and its receptor are known to play a role in regulating immune cells. However, how they affect an autoimmune disease like psoriasis is not well-established and the mechanism remains to be elucidated. Here, we investigated the role played by serotonin 2A receptor (HTR2A) in regulating psoriasis. HTR2A antagonistic drug worsens psoriatic outcome and HTR2A modulation reduced psoriatic inflammation. Using Imiquimod-induced psoriasiform inflammation model, HTR2A-deficient mice experienced exacerbated inflammation. Hematopoietic cells, particularly monocyte-derived Langerhans cells, were responsible for this exacerbated inflammation. Mechanistically, the exacerbated inflammation is due to increased interleukin-23 (IL-23) secretion and HTR2A suppresses it by inhibiting the activation of non-canonical NFkB pathway. Platelet-derived serotonin is the putative agonist modulating HTR2A attenuating psoriatic inflammation. Lastly, our findings in mice were also reproduced clinically. Thus, our data demonstrate platelet serotonin putatively modulates HTR2A attenuating psoriatic inflammation by suppressing IL-23 secretion via inhibiting non-canonical NFkB pathway in monocyte-derived Langerhans cells.

The serotonin transporter is a regulator of neurodegeneration and axon regeneration after retinal injury

Project description:Loss of specialized neurons in neurodegenerative diseases and after nerve injury is mediated in a neuronal subtype- and region-specific fashion. However, little is known about what molecular contexts define selective vulnerability. Here, we demonstrate that retinal ganglion cells (RGCs) in the mouse peripheral ventrotemporal (VT) retina are the most susceptible to optic nerve injury. Mechanistically, we show that the ventral-specific molecule, the serotonin transporter (SERT) is upregulated on VT axons within one day after injury and loss of SERT attenuates VT RGC death and promotes axon regeneration. From RNA-seq analysis, the transmembrane protein Gpnmb has been identified as a target downregulated by SERT. Moreover, GPNMB is involved in RGC protection and axon regeneration. Together, our studies reveal the serotonin transporter as a determinant of selective vulnerability.
