Brain-machine Interface for the Individualized Prescription of Assistance from Soft Robots
The project aims to use non-invasive brain imaging to "peak into the brain" of users with poststroke hemiparesis while they are walking with a garment-like, soft exosuit designed to help them move their legs. We hope to use this information to guide the prescription of the robotic assistance provided to individual users to maximize the orthotic or therapeutic effects of continuous use of the robot for gait assistance.

LSF-partner Protein Interactions Involved in Mitotic Progression
LSF is an oncogenic transcription factor that is required for tumor cells to appropriately progress through mitosis, resulting in cell division. Unexpectedly, this requirement for LSF does not involve transcriptional control, but rather interaction with partner proteins; we will identify key mitotic regulators that specifically bind LSF to uncover this novel mechanism.

Assessment of Efficacy of Serum Based Indices of Fracture Healing
This pilot project will build on our animal studies that identified 850 serum proteins that change over the time course of fracture healing. We will begin to translate these findings by validating human markers during humerus fracture healing to our preclinical studies, providing us with the human data to allow us to competitively develop a clinical trial for markers for normal and failed fracture healing.

Serotype Independent Protection against Pneumococcal Disease
We have used a new strategy to identify highly conserved, surface exposed, vaccine candidates for protection against the major bacterial cause of pneumonia and meningitis in children and adults. The CTSI project will evaluate proof of concept that immunization with these promising 'cold-spot' protein elicits protection against pneumococcal disease using an experimental chinchilla model.

The Effect of Fc Receptor Polymorphisms in the Pathogenesis of SLE
The goal of this proposal is to understand the mechanisms whereby the risk variant of Fc gamma receptor IIA is involved in immune cell activation and SLE pathogenesis. We will use immune cells from peripheral blood of lupus patients and healthy subjects, and stimulate them with sera from lupus patients which contains autoantibodies.

Cocaine Addiction Epigenetics
Dr. Huiping Zhang
and his collaborator Dr. Vidhya Kumaresan will investigate cocaine
use/withdrawal induced microRNA expression alterations in the brain's reward circuit using a translational rat model of incubated drug craving. It is expected that cocaine withdrawal responsive microRNAs could be potential biomarkers for CUDs and novel therapeutic targets.

FMT after Treatment for Clostridium Difficile
Fecal microbiota transplantation (FMT), now available via capsules without the requirement of an endoscopic procedure, restores the microbiome and has been highly successful in treating recurrent CDI but has had limited study for use after a primary CDI episode. We propose a proof-of-concept study to examine whether FMT administered after oral vancomycin therapy for primary CDI restores microbiome diversity and might be a viable strategy to improve outcomes.

A Novel Complement Fixation Assay for Prognosis in Membranous Nephropathy
The project seeks to answer the question of why there is often a disconnect between the titer of anti-PLA2R autoantibodies in primary membranous nephropathy and the severity and/or outcome of disease? We hypothesize that this may be due to the relative abilities of the subtypes of autoantibody to activate the different pathways of the complement system, and we plan to develop a simple assay to measure levels of complement activation by anti-PLA2R autoantibodies.

Assessing Opportunities for Tailored Risk Communication about Fentanyl Use
Dr. Gunn and her colleagues are using qualitative interviews to explore preferences about fentanyl-related risk communication among persons who have used fentanyl, examining differences by age and gender. The project will also describe the current strategies that community health workers use in talking to people about the high risk of overdose related to fentanyl use.

Developing an Online AOD Training Program
Health professionals are well positioned to identify and assist individuals experiencing problems with alcohol and other drug (AOD) misuse. Unfortunately, many health professionals are without the knowledge and advanced training needed to address AOD-related problems effectively. The goal of this study, designed to address this critical workforce shortage, is to advance the AOD-related knowledge and teaching skill of health professions educators.

Francesca Seta, MSC, PhD
Sirtuin-1 Against Aortic Aneurysm
This CTSI Pilot grant will support crucial studies in Dr Seta's laboratory that will examine the potential therapeutic effects of the protein sirtuin-1 in preventing aortic aneurysms by activating anti-inflammatory and anti-oxidant pathways in the vasculature. If these preclinical studies in animal models and human vascular cells will prove successful, sirtuin-1 activators could translate into novel therapies for the treatment and prevention of aortic aneurysms, a life-threatening vascular disease for which, currently, there are very limited therapeutic options.

Neutrophil Heterogeneity in Pneumonia
We will use flow cytometry cell
sorting and next generation RNA sequencing of individual cells in a murine model of pneumonia to test the
hypothesis that neutrophils recruited to the alveolar space are biologically distinct from the pulmonary
circulation and that within these two groups, subpopulations can be distinguished transcriptomally.

New Pathway Regulating the Harmful Inflammatory Phenotype of T cells
Uncontrolled inflammation underlies diseases such as diabetes, asthma, rheumatoid arthritis,
multiple sclerosis, Crohn's disease and inflammatory bowel disease. Using a mouse model, we
have identified a protein critical to repression of the inflammatory program in T cells. With the
help of the CTSI pilot award, we will translate what we have learned into human T cells. We
hope that these studies will define new pathways that are deregulated in inflammatory and
autoimmune diseases, leading to new therapies

3D Nanoladders
Inspired by the hierarchically organized axon bundles in the spinal cord white matter, we propose a nanoladder scaffold, composed of micrometer-wide fibers to provide directional guidance to the regenerated neurons, and nanometer-scale protrusions on each fiber serving as topographical cues to stimulate neurite outgrowth and synapse formation. We aim at developing a silk-based 3D nanoladder scaffold and demonstrate its efficacy in promoting axonal outgrowth and regeneration in a directional manner to promote functional restoration after spinal cord injuries.
