Abstract :

Aspergillus species, in the first place are ubiquitous fungi which ecologically tend to inhabit soil, water, vegetation and starchy products. Therefore they have an important effect on the global carbon and nitrogen reproduction chain. Also Aspergillus are well known opportunistic fungi that manipulate the immune system of human. Among the species, Aspergillus fumigatus is one of the most prevalent fungi which causes allergic forms of human disease and fatal aspergillosis. It has been previously shown that A. fumigatus has the following impacts on host cells: Once the conidia are inhaled, they would be phagocytosed by the epithelial cells of lung and localize into macrophages, developing aspergillosis and consequently as the infectious particles, they lead the cell entering into apoptotic phase. Also interestingly, the wild type melanotic conidia, can interfere with the intrinsic and extrinsic apoptotic pathways in macrophages and inhibit apoptosis. Since apoptosis is a pH-dependent event, in this study the effect of melanin from A. fumgatus on the pH variation during the apoptosis is hyperspectrally monitored in the human monocyte. Hyperspectral imaging (also known as imaging spectroscopy) is a research technique which collects and processes data from multiple fluorescent dyes in quantitative means. By applying this method, driven spectrum from multicolored fluorescent sample, is being divided into more extended bands and consequently, the visible and graphable images are provided.
