Meucci lab publishes review article on opioid and chemokine regulation of synaptodendritic damage in HAND

Pathways

Molecular pathways discussed in this article

The Meucci lab published a new review article that outlines the interplay between chemokine and opioid signaling and how these systems may regulate synaptodendritic damage in HIV-associated neurocognitive disorders (HAND). The article begins with a brief discussion of synaptodendritic damage in HAND and presents a small study on region-specific synaptic damage in two animal models of HAND. This is followed by a section on the mechanisms by which µ-opioid agonists contribute to synaptodendritic damage, and a discussion on exploiting the CXCL12-CXCR4 chemokine signaling axis to guide new therapeutic approaches that reverse dendritic spine deficits in HAND.

This article is part of a special issue published in Brain Research called “NeuroHIV in the current era: mechanisms and comorbidities contributing to cognitive impairment“, for which Dr. Meucci served as the guest editor.

The full-text article is available at Pubmed Central.

Meucci Lab publishes new collaborative study on the role of iron in neuronal opioid signaling

Visual abstractIn collaboration with Dr. Jonathan Geiger’s lab at the University of North Dakota, the Meucci lab recently published a new study describing how iron contributes to opioid-induced morphological changes in cortical neurons. Interestingly, morphine caused the release of iron stored in neuronal endolysosomes to the cytoplasm, which led to a post-transcriptional upregulation of the iron storage protein ferritin heavy chain. Increased ferritin heavy chain levels in these neurons was associated with a reduction of dendritic spine types that are thought to play important roles in learning and memory. Morphine-mediated dendritic spine deficits and ferritin heavy chain upregulation were completely blocked by selective chelation of endolysosomal iron, suggesting that these iron stores could be a new therapeutic target for opioid-using people at risk for developing cognitive impairment.

This study is featured and freely available in eNeuro, an open-access journal of the Society for Neuroscience.

Bologna Centrale

Dr. Brandimarti and Dr. Meucci Receive DUniBo 2019 Award

The University of Bologna has awarded Drs. Meucci & Brandimarti a grant to support the DUniBo initiative, which aims to increase student-centered scientific collaborations and other types of academic interactions between the University of Bologna and Drexel University. This new award will support an approximately six-month project known as The Student Ambassador, where students from each institution will spend 8-10 weeks abroad under the guidance of a faculty mentor and a fellow local student. Interested applicants should contact Dr. Meucci (om29@drexel.edu) and Dr. Brandimarti (renato.brandimarti@unibo.it) by February 25, 2019. Also see additional information.

Dr. Meucci Receives NIH MERIT Award

Dr. Meucci has been selected by The National Institute on Drug Abuse for a Method to Extend Research in Time (MERIT) award for the research grant: Role of chemokines in neuronal function and survival. The NIH MERIT program comprises an initial MERIT award and the opportunity for a five-year MERIT award extension, totaling up to 10 years of funding. MERIT awards are designed to provide long-term, stable support to investigators whose research competence and productivity are distinctly superior, and are awarded to less than 5% of NIH-funded investigators. Congratulations to Dr. Meucci for this great achievement!

Lindsay Festa

Lindsay Festa Defends PhD Thesis

Congratulations to Lindsay Festa for successfully defending her PhD thesis titled: Defining the molecular pathways involved in CXCL12-mediated rescue of dendritic spines and cognitive deficits in an animal model of neuroHIV. The quality and impact of Lindsay’s work has been recognized both locally and internationally, as evidenced by three publications in high profile peer-reviewed journals, numerous awards and honors, and her participation in international meetings. Lindsay established new techniques in the lab to study cognitive impairment in HIV-transgenic rats, and visualize dendritic spines in different contexts, which have contributed to two additional manuscripts currently in preparation.

Dr. Meucci awarded ISA fellowship at The University of Bologna.

The Institute of Advanced Studies has invited Dr. Meucci to spend a six-week fellowship on campus in an effort to foster international collaboration and global educational initiatives.  During her stay, she also presented a seminar entitled: “Three Key Questions on NeuroHIV: What is it?  Why Should We Care?  Can We Do Something?”

Lindsay Festa wins the Barry Waterhouse outstanding platform presentation award at Discovery Day 2017.

The award is given for first place in the platform presentation competition at Drexel’s Discovery Day.  Lindsay’s talk was titled: The chemokine CXCL12 restores dendritic spine loss and cognitive deficits in a rodent model of HIV-associated neurocognitive disorders.
