They discovered that this contact generates harmful free radicals in the cell, which drives the cell to self-destruct and release its NETs more quickly than it would otherwise. Due to low levels of antimicrobial proteins, Monteith‘s research team explored how neutrophils come into contact with staph bacteria and their mitochondria. The antimicrobial proteins from the NET then mix with antimicrobial proteins already in the macrophage’s stomach, thus together, the two cell types degrade bacteria more effectively than either cell could alone. “While gobbling down its catch, the macrophage is actually taking this giant bite out of the NET,” Skaar informs. Skaar claims neutrophils cast their NETs to immobilize the “bad guys.” Then, macrophages swoop in and swallow the bugs whole, not unlike how Pac-Man devours ghosts. suggests that the two cell types also team up to launch coordinated attacks against invasive microbes. In 2018, Zychlinsky and colleagues discovered neutrophil extracellular traps (NETs), which carry chemical red flags prompting macrophages to spark inflammation at an infection site, The Scientist reports. In these cells’ ultimate superhero crossover, Spider-Man-like immune cells sling webs to capture and kill invasive bacteria in order to keep those supervillains restrained until Pac-Man-like cells come to gobble them up, according to new research by Monteith et al. They indiscriminately engulf and eat almost anything deemed a dangerous trespasser, whether it’s a bacterium or cellular debris from deceased tissue. On the other hand, macrophages (white blood cells’ “munching” bacteria) are known for their ability to gobble up cellular debris and pathogens to thwart infection, being the “ Pac-Man” of the immune system and forming the body’s first line of defence against invasion. Because neutrophils die when engaging in this process, researchers consider the webs a cellular version of suicide bombing. However, occasionally neutrophils pull a Spider-Man maneuver, meaning they shoot sticky DNA webs and toxic proteins which ensnare pathogens and prevent them from spreading. These cells are often the first to arrive at the infection scene and attack invaders by gobbling up the intruders or ‘inviting’ other immune cells to fight. Firstly, there are neutrophils, which make up more than half of our white blood cells. Spider-Man-like immune cells sling webs to seize invasive bacteria and keep supervillains restrained until Pac-Man-like cells come to gobble them up.#Ī primary role of immune cells and proteins is to defend living organisms from invasions. Humans may never notice this superhero germ-fighting duo, yet they work wonders in the immune system.
