The C-terminus and Third Cytoplasmic Loop Cooperatively Activate Mouse Melanopsin Phototransduction

July 21, 2020
Author(s)
Juan C. Valdez-Lopez, Stephen T. Petr, Matthew P. Donohue, Robin J. Bailey, Meheret Gebreeziabher, Evan G. Cameron, Julia B. Wolf, Veronika Szalai, Phyllis R. Robinson
Melanopsin, an atypical vertebrate visual pigment, mediates non-image forming light responses including circadian photoentrainment and pupillary light reflexes, and contrast detection for image formation. Melanopsin-expressing intrinsically photosensitive

Quantitative Bright-Field Microscopy Combined with Deep Neural Networks Predict Live Tissue Function

February 29, 2020
Author(s)
Carl Simon Jr., Nicholas J. Schaub, Petru S. Manescu, Sarala Padi, Mylene Simon, Peter Bajcsy, Nathan A. Hotaling, Joe Chalfoun, Mohamed Ouladi, Qin Wan, Kapil Bharti, Ruchi Sharma
Progressive increases in the number of cell therapies in the preclinical and clinical phases has prompted the need for reliable and non-invasive assays to validate transplant function in clinical biomanufacturing. Here, we developed a robust

Characterization of the internal translation initiation region in monoclonal antibodies expressed in Escherichia coli

October 11, 2019
Author(s)
Erik M. Leith, William Brad O'Dell, Na Ke, Colleen McClung, Mehmet Berkmen, Christina Bergonzo, Robert G. Brinson, Zvi Kelman
Monoclonal antibodies (mAbs) represent an important platform for the development of biotherapeutic products. While most mAbs are produced in mammalian cells, there are several examples of mAbs made in Escherichia coli, including therapeutic fragments. When

Screening of Chemical Libraries Using a Yeast Model of Retinal Disease

September 26, 2019
Author(s)
Benjamin M. Scott
Retinitis pigmentosa (RP) is a degenerative retinal disease, often caused by mutations in the G protein-coupled receptor rhodopsin. The majority of pathogenic rhodopsin mutations cause rhodopsin to misfold, including P23H, disrupting its crucial ability to

Comparison of Artificial Intelligence based approaches to cell function prediction

July 11, 2019
Author(s)
Sarala Padi, Petru S. Manescu, Nicholas Schaub, Nathan Hotaling, Carl G. Simon Jr., Peter Bajcsy
Predicting Retinal Pigment Epithelium (RPE) cell functions in stem cell implants using non-invasive bright field microscopy imaging is a critical task for clinical deployment of stem cell therapies. Such cell function predictions can be carried out either

Structure and Function in Antimicrobial Piscidins: Histidine Position, Directionality of Membrane Insertion, and pH-Dependent Permeabilization

May 30, 2019
Author(s)
Mihaela Mihailescu, Mirco Sorci, Jolita Seckute, Vitalii I. Silin, Janet Hammer, B. Scott Perrin, Jorge Hernandez, Nedzada Smajic, Akritee Shrestha, Kimberly Bogadardus, Alexander Greenwood, Riqiang Fu, Jack Blazyk, Richard W. Pastor, Linda Nicholson, Georges Belfort, Myriam Cotten
Piscidins are histidine-enriched antimicrobial peptides that interact with lipid bilayers as amphipathic alpha-helices. Their activity at acidic and basic pH in vivo makes them promising templates for biomedical applications. This study focuses on p1 and

Innovative Approaches to Combat Healthcare-Associated Infections Using Efficacy Standards Developed Through Industry and Federal Collaboration

October 5, 2018
Author(s)
Dianne L. Poster, Carl C. Miller, Yaw S. Obeng, Michael T. Postek, Troy E. Cowan, Richard A. Martinello
Nation-wide, healthcare-associated infections (HAIs) infect one in every 25 hospital patients, account for more than 100,000 deaths and increase medical costs by around $96-147B, each year. Ultraviolet-C (UV-C) antimicrobial devices are shown to reduce the
