Why is myasthenia gravis called an autoimmune disease?

Do you have trouble closing your eyelids or chewing your food? Do you sometimes feel like gravity is pulling down on your muscles and draining all the energy out of them? If so, you may be one of the unlucky few who has been struck by a rare and perplexing disease known as myasthenia gravis (MG).

While most people have never even heard of MG, those who suffer from it know all too well how frustrating and debilitating it can be. But what exactly causes this strange disorder, and why do doctors label it as an “autoimmune” illness? Let’s dive in and find out.

Getting to Know Myasthenia Gravis

Before we tackle the complicated question of autoimmunity, let’s take a moment to understand just what MG is. At its core, MG is a neuromuscular condition that disrupts communication between nerve cells and muscle fibers. Essentially, the body’s own immune system attacks factors responsible for transmitting signals from nerves to muscles -how rude!

This leads to weakness and fatigue in various muscles throughout the body – including ones used for breathing – which can become quite dangerous if left untreated (like trying to hold back sneezes during allergy season).

MG symptoms typically come on gradually over time; many patients report having issues with their eyes (droopy lids) or mouth (difficulty speaking or swallowing) at first before other muscle groups start getting affected.

The Curious Case of Autoimmunity

Now that we’ve established what myasthenia gravis does, let us get into second gear . But why do medical professionals call MG an autoimmune disease anyways?

The concept behind “autoimmunity” goes something like this: normally ,the human immune system functions like a faithful soldier fighting against dangerous invaders such as bacteria,viruses etc trying protect our bodies. But sometimes, for reasons unknown , the immune system completely freaks out and starts attacking healthy cells and tissues within the body instead!!

This is essentially what happens in MG: for some mysterious reason, a patient’s immune system causes damage to specific molecules that are important for proper neuromuscular communication, misidentifying them as ‘enemies’.

A Look Inside The Attack

Okay okay,but how exactly do these attacks happen?

Normally (under normal circumstances), muscle function is dependent on an interaction between nerve impulses from the brain and receptors called acetylcholine (AChR) located at points where nerves meet muscles (neuromuscular junctions). With each nerve impulse that reaches this receptor point, AChRs can bind into contact with another protein known as MuSK which then signals “hey wake up” to those sleepy muscles .

However when a person has MG (unlucky soul!), there’s chaos! MG patients have special antibodies within their bloodstream – proteins whose purpose it is is to fight against specific foreign substances – who unfortunately target Ach-r or musk receptors. Suffice it so say ,this attack results in weaker neural transmissions rather than stronger ones! (Martial artists must envy stronger neural transmission- strong mind equals strong bones right?)

The partial blockade of neuromuscular junction activity because of chemical signal interference leads directly to the main symptom of myasthenia gravis : muscle weakness!

Autoantibodies Explained

We’ve mentioned “autoantibodies” a few times already; but what exactly are these funky little critters?I mean they sound like tiny soldiers you’d send off alone ! welllll…

Antibodies themselves are Y-shaped proteins created by white blood cells designed specifically to recognize unfamiliar compounds such as bacteria viruses etc which may otherwise cause harm . When interacting with harmful agents (infections,viruses,deepfakes..) , antibodies identify these compounds as foreign and then flag them for future destruction by the rest of the immune system’s assault teams.

Autoantibodies are a different story!] These little pipsqueaks – Auto meaning “self” – recognize healthy components of our own bodies (like AChRs in MG patients) as if they were foreign invaders to be eradicated . Yeah that’s right, antibodies literally turn on us!!

Why Does The Immune System Go Astray?

We’ve talked about what autoimmunity is;Let’s now address the elephant in the room :why do some people develop autoimmune diseases like myasthenia gravis while others remain unaffected? Well folks,the truth is that we still don’t know everything.Actually we know very little!

There are probably many factors at play here including genetics(which sometimes give nasty surprises), environmental factors like microbial infections and potentially unknown triggers from within your adaptive immune systems itself attempting to find new reasons for existing. However look out ! research is ongoing – who knows what crazy answers scientists might find next!

Where Do We Go From Here?

While it can be scary to have any illness or disease,knowing more about how our body works helps us stay ahead, understand symptoms better, and figure out which treatment plans may work best depending on said sickness or disease.So buckle up butter-cup because there could always be weirder things out there!!

MG continues to capture medical interest remains an enigma but tremendous strides have been made thanks to scientific curiosity especially when it comes treating via immunoglobin replacement therapies (IVIg). In general though, developing targeted treatments will help lead towards more effective remedies for those dealing with such unique conditions .

And last but not least,don’t forget about spreading awareness through education,pamphlets,videos etc. It serves as a way of communicating effectively so that we can all become conscious of people’s differences and needs in order to develop better medical care.
