Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Yeast filamentous growth is a stress response to conditions of nitrogen deprivation, wherein yeast colonies form pseudohyphal filaments of elongated and connected cells. As proteins mediating adhesion and transport are required for this growth transition, the protein complement at the yeast cell periphery plays a critical and tightly regulated role in enabling pseudohyphal filamentation. To identify proteins differentially abundant at the yeast cell periphery during pseudohyphal growth, we generated quantitative proteomic profiles of plasma membrane protein preparations under conditions of vegetative growth and filamentation. By iTRAQ chemistry and two-dimensional LC-MS/MS, we profiled 2,463 peptides and 356 proteins, from which we identified eleven differentially abundant proteins that localize to the yeast cell periphery. This protein set includes Ylr414cp, herein renamed Pun1p, a previously uncharacterized protein localized to the plasma membrane compartment of Can1 (MCC). Pun1p abundance is increased two-fold under conditions of nitrogen stress, and deletion of PUN1 abolishes filamentous growth in haploids and diploids; pun1D mutants are non-invasive, lack surface-spread filamentation, grow slowly, and exhibit impaired cell adhesion. Conversely, overexpression of PUN1 results in exaggerated cell elongation under conditions of nitrogen stress. PUN1 contributes to yeast nitrogen signaling, as pun1D mutants misregulate amino acid biosynthetic genes during nitrogen deprivation. By chromatin immunoprecipitation and RT-PCR, we find that the filamentous growth factor Mss11p directly binds to the PUN1 promoter and regulates its transcription. In total, this study provides the first profile of protein abundance during pseudohyphal growth, identifying a previously uncharacterized MCC protein required for wild-type nitrogen signaling and filamentous growth.

Description
CD19-specific CARs that comprise CD28 and CD3z signaling domains program highly performing effector functions that mediate potent tumor elimination, but they impart a relatively limited T cell lifespan. Increasing functional T cell persistence without reducing effector potency is therefore likely to further enhance the therapeutic success of 1928z CAR T cells. We demonstrate that the number and position of ITAMs in 1928z CAR T cells influence functional, phenotypic and transcriptional programs, resulting in profound effects on antitumor efficacy. Improved therapeutic potency of CAR T cells can thus be achieved by calibrating activation strength, thereby retaining memory functions and preventing exhaustion, without compromising effector functions. Our transcriptional analysis underscores the potential of ITAM dosage and position to direct different T cell fates. We were able to identify a novel CAR design, termed 1XX, which programs a favorable balance of effector and memory signatures, inducing increased persistence of highly functional CARs with the replicative capacity of long-lived memory cells and potent effector functions. Overall design: In order to assess the different phenotypic and functional patterns of CARs encoding a single immunoreceptor tyrosine-based activation motif (ITAM), we compared the genome-wide transcriptional profiles of 1928z, 1XX and XX3 after CD19 antigen stimulation of TRAC-edited naïve T cells. Sorted naïve (TN), stem cell memory (TSCM) and effector (TEFF) CD8+ T cells served as controls.

Description
Urinary tract infections (UTIs) constitute a highly relevant model of microbial adaptation, in which the contrasting effects of pathogens and commensals on host tissues are clearly displayed. While virulent Escherichia coli cause severe, potentially life-threatening disease by breaking the inertia of the mucosal barrier and infecting the kidneys, the most common outcome of bacteriuria is an asymptomatic carrier state resembling commensalism at other mucosal sites. It remains unclear if the lack of destructive inflammation merely reflects low virulence or if carrier strains actively inhibit disease associated responses in the host. To address this question, we examined the effects of asymptomatic bacterial carriage on host gene expression.
