Dr. Qin Wang's research interests revolve around investigating cell surface receptor signaling and neuropharmacology in the context of brain physiology and disease pathology. Her laboratory employs state-of-the-art techniques, including CRISPR editing, multiomic analysis, super-resolution imaging, pharmacological and behavioral approaches, as well as humanized animal models, human postmortem tissues, and iPSC-derived brain cells, to elucidate the molecular and cellular mechanisms underlying Alzheimer's disease (AD) and complex behaviors. Furthermore, the lab explores the therapeutic potential of targeting these mechanisms for disease treatment, with the ultimate goal of translating their fundamental discoveries into novel clinical applications.
One of the primary focuses of Dr. Wang's lab is AD, a multifaceted disease that involves numerous genetic and environmental factors. Her lab employs a multifaceted approach to address this complexity, with a particular emphasis on the following areas: 1) exploring the contribution of noradrenergic dysfunction to AD pathogenesis; 2) investigating alterations in endosomal trafficking in AD and the interactions between AD risk factors; 3) elucidating the role of astrocytic signaling and reactivity in AD progression; 4) examining the relationship between AD risk and cancer therapies, as well as congenital heart diseases; 5) developing treatments for AD by targeting neuronal hyperexcitability.
Some of our focus are:
1. Molecular and cellular mechanisms underlying Alzheimer’s disease (AD) pathogenesis
a) noradrenergic dysfunction and adrenergic signaling in AD;
b) regulation of endosomal trafficking and its involvement in AD pathogenesis;
c) astrocyte reactivity in AD;
d) tumors and related therapies as risk factors for AD.
2. Cognition and complex behaviors
a) synaptic signaling in autism;
b) epigenetic regulation of anxiety and
c) a novel mouse model for ADHD.
3. Selective targeting of GPCRs
a) neural-specific enhancement of adenosine receptor for neuroprotection;
b) signaling-specific targeting of adrenergic receptor for AD.

Multiple NIH-funded postdoctoral positions are available for motivated and creative postdoctoral fellows to study disease mechanisms at molecular, cellular and system levels and to identify novel therapeutic strategies for neurological disorders. Excellent research techniques in biochemistry and molecular biology are preferred.
Prior experience with brain research and skills in computation are valued. Candidates with biochemistry, cell biology and/or neurobiology backgrounds are encouraged to apply. The laboratory focuses on translational research in synaptic signaling and neuropharmacology.
The postdoctoral fellow will have opportunities to conduct the innovative research projects with state-of-the-art technologies and model systems, such as CRISPR gene editing, single-cell RNA-Seq, super-resolution imaging, AI-aided design and analysis, patient-derived iPSCs and humanized mouse models.
The fellow will be given opportunities to apply for training grants and encouraged to pursue independent research career, with a strong support from the mentor.
Postdoctoral Fellows:
We seek postdoctoral fellows interested in studying Alzheimer’s disease. The candidates
will hold a PhD or MD or equivalent in neuroscience, physiology, molecular/cell biology,
biochemistry or neuropharmacology. Expertise in molecular biology and biochemistry
is desirable. Candidates are expected to have good communication skills and have a
strong drive for building a successful research career.
Graduate Students:
We welcome graduate students and are interested in potential rotation students. Prospective
students can apply to our lab through the Graduate Program in Neuroscience as well
as through the MD/PhD Program.
Undergraduate Students and medical students:
We accept motivated undergraduate students and medical students who are interested
in biomedical research.

Continue ReadingResearchers at the Medical College of Georgia at Augusta University are searching for a better way to understand why many men with prostate cancer end up with Alzheimer's disease, and whether it's the standard hormone therapy treatment or an overactive immune response that actually contributes to the problem. The hormone therapy, androgen deprivation therapy, known as ADT, treats the cancer by reducing testosterone, which the cancer needs to grow. But androgen is a key regulator of amyloid metabolism and when it's removed from the equation, more amyloid is left to form the plaques that are a hallmark of Alzheimer's.
