Antikörper
🔬 What exactly is an Antikörper?
An Antikörper (antibody; chemically usually an Immunglobulin or immunoglobulin) is a protein produced by the immune system in response to specific substances called Antigene (antigens), e.g., from viruses or bacteria. Antikörper bind specifically to these antigens, helping to neutralize pathogens or mark them for other immune cells.
They are a central part of the adaptive immune response and play a crucial role in defending against infections and in immunity.
The word Antikörper only uses the article der (masculine). ⚠️ Confusion with other immunology terms is possible, but the article is clearly masculine.

🧠 Mnemonics and Memory Aids
Article Mnemonic: Think of 'der' defender of the Körper (body). The Antikörper is like a little soldier (masculine - 'der') defending the body.
Meaning Mnemonic: Anti means 'against', and Körper here refers not to the whole body, but to a 'foreign body' (antigen) or a 'body' (protein) in the blood that fights against something. So, a fighter protein against invaders.

📜 Little Poem about the Antikörper
DE:
Im Blut, da schwimmt ein kleiner Held,
Der Antikörper, gut bestellt.
Kommt ein Feind, ein Virus klein,
Dockt er an und sagt: "Nicht rein!"
Er markiert ihn, ruft zur Wehr,
Schützt den Körper, immer mehr.
EN:
In the blood, a little hero swims,
The antibody, well-equipped it seems.
If a foe, a virus small, draws near,
It docks on and says: "You don't enter here!"
It marks it, calls the defense to fight,
Protecting the body, day and night.
❓ Little Riddle
DE:
Ich bin ein Protein, vom Körper gemacht,
habe über Eindringlinge stets gewacht.
An Antigene binde ich mich fest,
und helfe dem Immunsystem beim Test.
Wer bin ich?
EN:
I am a protein, made by the body's might,
Always watching over invaders, day and night.
I bind tightly to antigens, it's true,
And help the immune system see things through.
What am I?
