Phagocytosis of fungus spores, SEM
Phagocytosis of fungus spores. Coloured scanning electron micrograph (SEM) of spores from the fungus Aspergillus fumigatus (red) being phagocytosed (engulfed and destroyed) by a dendritic cell (brown). Dendritic cells are antigen presenting cells (APCs) that present the digested parts of phagocytosed pathogens to other immune system cells. Aspergillus fumigatus is common in dust, soil, and on plants and plant products such as hay or grain. It can cause a number of different diseases in humans, including allergic disorder, respiratory infection and invasive disease

EDITORS COMMENTS
This print captures the intense battle between a dendritic cell and fungus spores. In this coloured scanning electron micrograph (SEM), we witness the process of phagocytosis, where the dendritic cell engulfs and destroys the red-coloured spores from Aspergillus fumigatus. Dendritic cells play a crucial role in our immune system as antigen presenting cells (APCs). They digest parts of pathogens they have engulfed and present them to other immune system cells. This interaction is vital for mounting an effective immune response against invading pathogens. Aspergillus fumigatus, commonly found in dust, soil, plants, hay or grain, can cause various diseases in humans. These include respiratory infections, allergic disorders, and even invasive diseases. Understanding how our immune system combats such fungal infections is essential for developing effective treatments. The intricate detail captured by this SEM image highlights the complexity of cellular interactions during phagocytosis. The false colouring adds depth to the image while emphasizing key elements like defense mechanisms and infection control. This photograph not only showcases the beauty of biology but also serves as a reminder of our body's incredible ability to defend itself against harmful invaders. It provides valuable insights into immunology and microbiology research that could potentially lead to advancements in medical treatments targeting fungal infections.
