Yes, because they’re MHC compatible.
awesome! Fuck yeah, repping bio and medical physics!
This is an electron micrograph of a neutrophil engaging in phagocytosis of anthrax bacteria. The larger, yellow, irregularly shaped object is the neutrophil, and the orange rods are anthrax bacteria.
Neutrophils are the main cell type responsible for innate[as opposed to acquired] immunity, and provide our day to day defenses against pathogens which we have never encountered before, and hence have no antibodies to, as well as covering the lag time necessary for antibodies to be “deployed” upon re-challenge.
They also have a very important role in wound healing, as they also undertake phagocytosis of dead cells, cleaning them up and mitigating the ability of necrotic tissues to cause further necrosis.
Neutrophils are generally the most important immune cell in the body, with neutropenia from any cause [i.e. medications] being a grave risk associated with high mortality due to overwhelming infections.
Geobacter metallireducens is a rod shaped gram negative anaerobic bacterium which can use metals and organic compounds found in petroleum as a terminal electron acceptor in its metabolic processes. Seen in this photo with Iron(III)Oxide it can also utilize a wide variety of other metals, including Uranium. Due to its ability to convert petroleum products into harmless Carbon Dioxide, it is useful in bio-remediation of petrol contaminated lands, as well as to precipitate uranium out of contaminated water in anoxic locations as it is an anaerobe.
