Create a minimalist illustration of glial cells interacting with neurons. Use soft pinkish and reddish tones for the glial cells and light grey with soft blue highlights for the neurons. The background should be a smooth gradient transitioning from deep black to dark purple and pink, creating depth without overwhelming the simplicity of the design. The cells should be abstract but recognizable, with glowing elements to suggest activity. The overall style should be clean, modern, and scientific, with a focus on simplicity and elegance."
