Both sepsis and acute respiratory distress syndrome (ARDS) rely on imprecise clinical definitions leading to heterogeneity, which has contributed to negative trials. Because circulating protein/DNA complexes have been implicated in sepsis and ARDS, we aimed to develop a proteomic signature of DNA-bo...
The growing field of urinary proteomics has provided a promising opportunity to identify biomarkers useful for diagnosis and prognostication of a number of diseases. Urine is abundant and readily collected in a non-invasive manner which makes it eminently available for testing, however sample prepar...
The capacity for T cells to become activated and clonally expand during pathogen invasion is pivotal for protective immunity. Our understanding of how T cell receptor (TCR) signaling prepares cells for this rapid expansion remains limited. We have identified an E3 ubiquitin ligase, Cul4b, that regul...
Accumulation of aggregated α-synuclein into Lewy bodies is thought to contribute to the onset and progression of dopaminergic neuron degeneration in Parkinson’s disease (PD) and related disorders. Although protein aggregation is associated with perturbation of proteostasis, how α-synuclein aggregat...

To mount an anti-pathogen response, CD4 T cells must undergo rapid cell proliferation. However, poorly controlled expansion can result in diseases such as autoimmunity. One important regulator of T cell activity is the E3 ubiquitin ligase Itch. Itch deficient patients suffer from extensive autoinfla...
Ig diversification occurs in peripheral lymphoid organs after establishment of central tolerance during B cell development. In germinal centers (GCs), somatic hypermutation of Ig genes occurs in dark zones, followed by selection of mutated clones in light zones (LZs). This generates high-affinity Ig...
Nitric oxide (NO) is an important signaling molecule in the cardiovascular system. Reduced bioavailability of NO results in debilitated signaling, which contributes to the pathogenesis of cardiometabolic disorders. However, the alterations in signaling under NO deficiency remain mostly unknown. T...
We isolated resting platelets from full term umbilical cord blood and adult peripheral blood. We used DIA mass spectrometry to analyze the whole proteome and phosphoproteome from this platelet samples.
