MHC class I polypeptide-related sequence B (MICB) is a ligand for NKG2D. We have shown NK cells are central to lung transplant acute lung injury (ALI) via NKG2D activation, and increased MICB in bronchoalveolar lavage predicts ALI severity. Separately, we found a MICB polymorphism (MICBG406A) is associated with decreased ALI risk. We hypothesized this polymorphism would protect against severe SARS-CoV-2 respiratory disease. We analyzed 1,036 patients hospitalized with SARS-CoV-2 infection from IMPACC. Associations between MICBG406A and outcomes were determined by linear regression or Cox proportional hazards models. We also measured immune profiles of peripheral blood and the upper and lower …

Clonal hematopoiesis (CH) is associated with many age-related diseases, but its interaction with Alzheimer's disease (AD) remains unclear. Here, we show that TET2-mutant CH is associated with a 47% reduced risk of late-onset AD (LOAD) in the UK Biobank, whereas other drivers of CH do not confer protection. In a mouse model of AD, transplantation of Tet2-mutant bone marrow reduced cognitive decline and β-amyloid plaque formation, effects not observed with Dnmt3a-mutant marrow. Bone-marrow-derived microglia-like cells were detected at an increased rate in Tet2-mutant marrow recipients, and TET2-mutant human induced pluripotent stem cell (iPSC)-derived microglia were more phagocytic and hyperinflammatory than …

Traditional anti-inflammatory medications-such as corticosteroids, biological agents, and non-steroidal anti-inflammatory drugs-are commonly employed to mitigate inflammation, despite their potential for debilitating side effects. There is a growing need for alternative next-generation therapies for symptomatic, unchecked, and/or detrimental inflammation with more favorable adverse effect profiles. The long history of use of gold salts as anti-inflammatory agents and the more recent exploration of gold nanoparticle (AuNP) formulations for clinical indications suggest that the targeted delivery of nanoparticles to inflammatory sites may be a promising approach worth investigating. Coupled with peptides that specifically target immune cells, AuNPs could potently counteract inflammation. Here, we …

Specificity Of Interaction Of Antimicrobial Peptide With Cell Membrane, Srishhti Kumar Jha

Pharmaceutical Sciences (MS) Theses

Antimicrobial resistance (AMR) is an increasing global health threat due to its rising incidence worldwide. Resistant microbial infections have become difficult to treat and pose serious risks to patients. In 2019, AMR was responsible for approximately 1.27 million deaths globally, with numbers continuing to rise. The World Health Organization (WHO) has highlighted the urgent need for new antibiotics with novel mechanisms of action and low toxicity to combat this issue. Antimicrobial peptides (AMPs) represent a promising solution. These peptides exhibit broad-spectrum antimicrobial activity and rapid killing kinetics, reducing the likelihood of resistance development. AMPs primarily target bacterial cell membranes. Their …

Cbl Regulation Of C-Met Signaling In Corneal Epithelial Cells., Kate Elise Tarvestad Laise

Electronic Theses and Dissertations

The cornea is the most anterior portion of the eye and permits light passage through to retina, allowing formation of a clear image as long as it remains healthy. If the cornea sustains damage, it creates and entrance for foreign body invasion, infection, and ultimately blindness in the immunocompromised eye. Healing the corneal tissue is critical for vision restoration and pain alleviation, as it is the most densely innervated tissue in the body. Growth factors and their cognate receptors are currently under investigation as tools to restore proper corneal physiology. We hypothesize that manipulating the hepatocyte growth factor (HGF) /c-Met …

Massively Parallel Immunopeptidome By Dna Sequencing Provides Insights Into Cancer Antigen Presentation, Quanming Shi, Cheryl F Lichti, Et Al.

2020-Current year OA Pubs

Human leukocyte antigens (HLAs) are encoded by the most polymorphic genes in the human genome. HLA class I alleles control antigen presentation for T cell recognition, which is pivotal for autoimmunity, infectious diseases and cancer. Current knowledge of HLA-bound peptides is limited, skewed and falls short of population-wide HLA binding profiles for high-value targets. Here we present ESCAPE-seq (enhanced single-chain antigen presentation sequencing), a massively parallel platform for comprehensive screening of class I HLA-peptide combinations for antigen presentation via deep DNA sequencing. ESCAPE-seq demonstrates programmability, high throughput, sensitivity and nominated viral and cancer epitopes. We simultaneously assessed over 75,000 peptide-HLA …
