In the Biowars comic book, macrophages are personified as Phagien<\/a><\/strong> and Scathe<\/a><\/strong> \u2014 the fearless warriors ready to tackle just about any mutant and microbe<\/a>.<\/p>\n But what are macrophages exactly? What functions do they perform in our body, and how do they protect us?<\/p>\n Let\u2019s find out what makes macrophages essential to our body!<\/p>\n Read the BioWars comic book!<\/a><\/p>\n Macrophages Phagien and Scathe devour the enemy imposing danger to the Bioverse.<\/p><\/div>\n Macrophages are the \u201cbig eaters\u201d<\/strong> within your immune system<\/strong>. Their name comes from the Greek word \u201cmakr\u00f3s,\u201d which means \u201clarge\u201d and \u201cphagein\u201d \u2014 \u201cto eat.\u201d<\/p>\n Now, when we say that macrophages are big eaters, we\u2019re talking about the \u201cdevouring the all-you-can-eat hotel buffet\u201d kind of appetite. The hunger of other BioWarriors doesn\u2019t even come close to that of macrophages!<\/p>\n As a white blood cell, macrophages have a clear goal \u2014 to keep you in good health<\/strong>. But unlike other white blood cells who carefully plan attacks on intruders, macrophages don\u2019t overthink their actions. Upon detecting intruders, they immediately spur into action! Their motto is simple \u2014 seek and destroy!<\/p>\n Whether it\u2019s attacking microbes and cancer cells<\/a> or disintegrating cellular debris and other foreign substances, the macrophages\u2019 primary function is to engulf, digest and purge anything that doesn\u2019t belong inside your body<\/strong>. This process is known as phagocytosis.<\/p>\n Meet the characters of the Bioverse!<\/a><\/p>\n Phagocytosis is a merciless act during which phagocytes devour other cells and infected agents.<\/p>\n Phagocytes include three types of white blood cells:<\/p>\n When a macrophage spots something that doesn\u2019t appear to be healthy or could potentially cause some damage to the immune system, it heads out to find the suspicious agent.<\/p>\n Macrophages are on the lookout for certain types of proteins specific to healthy body cells.<\/strong> If a macrophage warrior finds such proteins on a cell, it leaves the cell alone and moves on. If it doesn\u2019t detect the proteins on the surface of a cell, then it pulls out the forks and napkins and prepares for a virtual smorgasbord<\/strong>!<\/p>\n To make the process of phagocytosis clearer, let\u2019s look at the image below:<\/p>\n [Source: Neuroscience News<\/a>]<\/p><\/div>The process starts when a macrophage surrounds its prey with a mouth-like protrusion (see item \u201ca\u201d) that consumes pathogens (see number \u201c1\u201d).<\/p>\n Once pathogens enter a macrophage, phagosomes surround them (see number \u201c2\u201d). Then, phagosomes fuse themselves together with lysosomes (see number \u201c3\u201d) only to begin breaking them down.<\/p>\n The body that was formed once phagosomes and lysosomes became one is called a phagolysosome<\/strong> (see step \u201cb\u201d).<\/p>\n When this dynamic duo combines their powers, pathogens just don\u2019t stand a chance!<\/strong> Phagolysosome\u2019s enzymes can quickly break the enemy down (see number \u201c4\u201d).<\/p>\n At this point, what else can you expect from macrophages other than to get rid of the waste material (see step \u201cc\u201d) and prepare for the next course?<\/p>\n Not a darn thing, because that\u2019s exactly what happens next! The waste is eliminated from the cytoplasm (see number \u201c5\u201d) through the cell membrane (see number \u201c6\u201d). From there, the bloodstream carries it away from the cell.<\/p>\n And that\u2019s how phagocytosis works!<\/strong><\/p>\n Learn more fun facts about your body!<\/a><\/p>\n The exact purpose of macrophages in your body depends on what tissue or organ they belong to.<\/p><\/div>\n Macrophages do a lot more than just take out the bad guys. Their functions are plentiful and fascinating.<\/p>\n Whenever your muscles need repairing after you overuse or injure them, macrophages are there to help you regenerate your muscle fibers<\/strong>.<\/p>\n Macrophages also do a lot in terms of wound healing<\/strong>. They usually show up in massive numbers at the scene to lure other types of healing cells to the area, including fibroblasts<\/a>. Once they all arrive at the wound, they work as a team to heal your body both from the inside and outside.<\/p>\n The functions of macrophages don\u2019t end there, though. Macrophages patrol nearly every corner of your system and play a big part in your innate immune system.<\/strong> Alongside neutrophils and the Natural Killer Cells<\/a>, they represent the first line of defense against infections.<\/p>\n As part of the innate immune response, macrophages team up with lymphocytes to exterminate viruses and diseases<\/strong>. They also release cytokines \u2014 small proteins that impact the activity of other cells. Cytokines are like biological bat signals that tell the immune system it needs to get cranking at full speed to eliminate threats!<\/strong><\/p>\n Another interesting thing about macrophages is their ability to regenerate lost limbs in some animals, such as salamanders<\/a>.<\/strong><\/p>\n While macrophages may not be able to do this for humans yet, there\u2019s a good chance that scientists might one day discover a way to restore parts of the body by relying on the restorative activity of macrophages.<\/p>\n Meet the bad guys from the Biowars comic book!<\/a><\/p>\n If we were to compare macrophages to an insect or an animal, ants would be the best fit.<\/p>\n Just like ants, macrophages are small, mighty and incredibly diverse<\/strong>. Moreover, different types of macrophages perform different tasks to make the whole immune system work like a clock \u2014 much like ants in ant colonies.<\/p>\n To explain how it is possible for macrophages to be so multi-functional, let\u2019s explore where they come from first.<\/p>\n Macrophages\u2019 closest relatives in your body are monocytes \u2014 a type of white blood cells that originates in your bone marrow.<\/strong><\/p>\n These large cells travel all over your body via your blood vessels until they arrive at specific organs or tissues. There, they transform into macrophages with the help of special proteins called cytokines.<\/p>\n Because they serve a specific purpose in their respective organs or tissues of destination, macrophages in one part of your body are different from macrophages in other parts. Here are just a few examples:<\/p>\nWhat Are Macrophages?<\/h2>\n
