Actin tail, fluorescent micrograph
Actin tail. Immunofluorescence deconvolution micrograph of a close-up of an actin filament (green) in a cell infected with vaccinia virus particles. Actin is part of the cytoskeleton, which allows some cellular mobility and is involved in intracellular transport. A tyrosine kinase protein, c-Abl (red), is seen at the tip of the tail. C-Abl is involved in catalysing actin motility. Several viruses use actin tails to propel newly formed particles out of the host cell towards neighbouring uninfected cells

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate details of an actin tail, a crucial component of cellular mobility and intracellular transport. The immunofluorescence deconvolution micrograph reveals a close-up view of an actin filament in a cell infected with vaccinia virus particles. Actin, represented by the vibrant green color, forms part of the cytoskeleton and plays a vital role in facilitating movement within cells. At the tip of this mesmerizing actin tail, we observe the presence of c-Abl, a tyrosine kinase protein indicated by its striking red hue. C-Abl is known to catalyze actin motility, further emphasizing its significance in cellular processes. Interestingly, numerous viruses exploit actin tails as propellers to expel newly formed viral particles out of host cells towards neighboring uninfected cells. This phenomenon highlights how viruses manipulate host cell machinery for their own propagation and dissemination. The image's exceptional level of detail was achieved through advanced imaging techniques such as immunofluorescence and confocal microscopy. By utilizing fluorescent dyes that specifically bind to target proteins or structures within cells, scientists can visualize these microscopic components with remarkable precision. Science Photo Library continues to provide invaluable resources like this photograph for researchers and enthusiasts alike who seek to unravel the complexities of biology and medicine.
