Background

Allergic fungal rhinosinusitis (AFRS) is a severe subtype of chronic rhinosinusitis characterized by fungal hypersensitivity and accentuated type 2 inflammation. Dupilumab-a fully human monoclonal antibody blocking interleukin-4/13, approved for type 2 inflammatory diseases, including chronic rhinosinusitis with nasal polyps-may benefit patients with AFRS.

Objective

We sought to understand the effect of dupilumab in AFRS

Methods

In this phase 3 trial, patients with AFRS aged ≥6 years were randomized to dupilumab or matched placebo for 52 weeks. The primary end point was Lund-Mackay computed tomography (LMK-CT) score, quantifying sinus opacification, at 52 weeks. Secondary end points were multiplicity-controlled and hierarchically …

A Case Displaying The Importance Of Jak1 And Jak2 Gene Transcription In Antifungal Defense Against Coccidioidomycosis, Jennifer K. Priessnitz, Taylor Colore, Nelson Nicolasora

Department of Medicine Faculty Publications

This case report explores the consequences of ruxolitinib via inhibition janus kinase 1 (JAK1) and JAK2 pathways in the context of fungal defense in a patient diagnosed with pulmonary coccidioidomycosis during ruxolitinib therapy for polycythemia vera. The patient experienced a relapse of pulmonary coccidioidomycosis after antifungal treatment was discontinued while continuing ruxolitinib use. This case illustrates the heightened risk of discontinuing antifungal therapy in endemic regions, emphasizing the critical need for continued monitoring. Furthermore, this case underscores the vital role of the JAK1 and JAK2 signaling cascade, particularly the interferon-gamma (INF-γ)-JAK1 and JAK2-signal transducer and activator of transcription 1 (STAT) …

Natural And Synthetic Viniferins Associated With The Grapevine Disease Young Vine Decline, David Michael Mcginnis

Chemistry & Biochemistry Theses & Dissertations

Grapevine disease has been thc subject of intense research amongst viticulturists over the last few decades, especially during the 1990's. There has been discoveries that suggest grapevine disease is commonly caused by fungal pathogens. One of the most common fungi that the vine may become infected by is known as Botrytis cinerea. B. cinerea is capable of attacking the grapevine which in turn will lead to bunch rot in the grape clusters. This disease has been researched in great detail during the past several years and is one of only few microorganisms that have actually been identified. Phaeoacremrmium chnlmydospnrum …

Biodegradation Of Crude Oil By Marine Higher Fungi, Brian J. Dyer

Biological Sciences Theses & Dissertations

Four experiments were performed to determine the ability of marine higher fungi to grow in and degrade crude oil. Eight species, previously determined to be hydrocarbonoclastic, were grown in artificial sea water medium (ASM) and southern Louisiana crude oil. The dry mycelial weights were measured and consumption of crude oil was measured gravimetrically. The two species with the best growth, Corollospora maritima and Zalerion maritimum, were grown in ASM containing crude oil spiked with three known hydrocarbons. To this was added glucose (0.15%) and incubated 49 days to test for possible cometabolism of hydrocarbons. Hydrocarbons remaining in the growth …

A Potential Macroregulatory Mechanism For Growth Regulation In Neurospora Crassa, Martha Mooney

Biological Sciences Theses & Dissertations

Neurospora produces a phase specific, cationic mucopolysaccharide composed primarily of galactosamine (GAG-MP) which becomes part of the cell wall and is later secreted into the media. Its appearance coincides with the onset of the restricted phase of growth and causes efflux of small molecular weight metabolites when incubated with conidial cells. This activity may be a product of electrostatic interactions of the GAG-MP with the conidial plasma membrane. The activity is blocked by acetylation of the primary amines on the molecule, digestion by enzymes that hydrolyze carbohydrate linkages and the inclusion of NaCl (lM) in the GAG-MP/conidia reaction mixture. The …

Demonstration Of Unique Mycelial Components In Candida Albicans, David Jon Mancuso

Biological Sciences Theses & Dissertations

Mycelial (M) and blastopore (B) cell homogenates of Candida albicans strain BJ85 were compared to detect and recover unique M components. Qualitative differences in the protein and lipid content of Mand B homogenates were suggested by discontinuous polyacrylamide gel electrophoresis (DPAGE). In addition, a quantitative and possibly qualitative shift in the protein content during germ tube formation was implied by DPAGE. Unique M components were detected using both DPAGE and immunoelectrophoretic (IE) techniques. One unique M component by DPAGE, four by IE, and two by combined DPAGE and IE techniques were suggested. Of these three methods, only DPAGE and the …

Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoretic Studies Demonstrating Cytoplasmic Protein Components Unique To The Mycelial Phase And To The Yeast Phase Of Candida Albicans, Theresa Catherine Burgess

Biological Sciences Theses & Dissertations

Blastospore and mycelial cytoplasmic extracts from four strains of Candida albicans, varying in virulence, were compared by sodium dodecyl sulfate (SDS) polyacrylamide disc gel electrophoresis Cytoplasmic extracts were made by disrupting the cultures in a Braun homogenizer followed by ultracentrifugation. The supernatant fractions were then resolved on polyacrylamide gels containing SDS. Each of the preparations yielded a distinct pattern. There were mycelial specific and blastospore specific protein bands. There were more components resolved from the blastospore phase cytoplasmic extracts than from the mycelial phase cytoplasmic extracts. There were bands common to both phases. These results demonstrate protein components unique …
