Transcription profiling of Aspergillus fumigatus Af293 after temperature shifting

Project description:Experimental factor: Time after the temperature shift from 30C to 37C or 30C to 48C. Conidia (5x106 /ml) from Aspergillus fumigatus Af293 were incubated in the CM medium for germination (~ 17 hrs) at 30C. The culture was transferred to a water bath of 37C or 48C for continued growth. Samples were taken after the defined time (i.e. 0, 15, 30, 60, 120, and 180 min.).

Next Generation Sequencing of HUVECs stimulated by conidia of Aspergillus fumigatus

Project description:Purpose: The goal of this study is to investigate the responses of HUVECs after the stimulation of conidia of A. fumigatus Methods: HUVECs were stimulated with conidia of Aspergillus fumigatus for 2 and 6 hours. Three biological repeats of stimulated cells or un-stimulated controls were send for RNA sequencing. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the human genome (build hg38) and identified round 80,000 transcripts in the HUVECs upon stimulation. Conclusions: Our resutls showed the detailed analysis of HUVECs transcriptomes upton conidia of Aspergillus fumigatus stimulation.

Temperature during conidiophore development primes Aspergillus fumigatus spore transcriptome for asexual or sexual development

Project description:Aspergillus fumigatus is a thermotolerant saprobe found in soils and plant debris worldwide and an important pathogen of humans causing two million deaths annually. A. fumigatus makes abundant asexual spores (conidia) which are widely distributed by wind and can be inhaled from the environment. In susceptible individuals inhaled conidia break dormancy, germinate and grow in the lung leading to serious disease. Recent work has shown that conidia made at 37°C and 50°C have different morphologies and germination kinetics. While the asexual cycle is well-characterized at 37°C, much less is known about the asexual cycle at 50°C. Here, we combine flow cytometry and transcriptomics to track morphology and gene expression in the hyphae, conidiophores and conidia of A. fumigatus during asexual development at 37°C or 50°C. We show that the temperature during a narrow time window in late-stage conidiophore development dictates resulting conidial morphology, transcriptional program, and germination kinetics. As expected, conidiation at 37°C resulted in upregulation of brlA, the master regulator of asexual development, and its downstream targets in conidiophores and conidia. Surprisingly, conidiation at 50°C resulted in upregulation of MAT1-1, the master regulator of sexual development and its downstream targets in conidiophores and conidia. Our findings suggest that temperature during late conidiophore development transcriptionally primes conidia for asexual, parasexual or sexual development enhancing chances of survival for progeny. Our findings are especially relevant for agricultural compost where a wide gradient of temperatures exists, abundant A. fumigatus has been isolated, and resistance to antifungals is thought to evolve.
