Toll-like receptor necklace | sterling silver
If you can name which TLR recognises which PAMP, this one's for you. Toll-like receptors are how the immune system tells, within seconds, that something has gone wrong, before any antibody has been made.
The Science of Pattern Recognition Receptors
Toll-like receptors (TLRs) are the front line of innate immunity. They sit on immune cells and epithelial surfaces and detect conserved microbial structures, the pathogen-associated molecular patterns: lipopolysaccharide on Gram-negative bacteria, flagellin on motile species, double-stranded viral RNA, unmethylated CpG DNA, and more. Engagement triggers signalling through MyD88 or TRIF, which activates NF-κB and the interferon regulatory factors and switches on the cytokine programme that brings the rest of the immune system in. The discovery of TLRs in mammals as the orthologues of the Drosophila Toll receptor earned Jules Hoffmann and Bruce Beutler a share of the 2011 Nobel Prize in Physiology or Medicine.
Who Will Recognise It
The audience is narrow, peer-recognition territory:
- innate immunologists and inflammation researchers
- vaccinologists working on TLR-based adjuvants
- sepsis researchers and intensivists who've seen what dysregulated TLR signalling does
- immunology students who have just memorised which TLR sees what
Most often bought as a peer gift inside immunology departments or by lab heads marking a postdoc's first paper.

FAQ
Will this register with someone outside immunology?
Probably not in the same way. Toll-like receptors are specialist territory, and the recipient ideally already knows what a PAMP is. For a more general immunology piece, the macrophage or lymphocyte necklaces work better.
Why are TLRs considered the bridge between innate and adaptive immunity?
Because they signal both arms at once. TLR engagement on dendritic cells activates the cell's antigen-presentation programme and pushes it to the lymph node, where it primes T cells. The same signal that triggers an immediate cytokine response also licenses the slower adaptive response that comes hours and days later. No TLR signal, no efficient adaptive immunity.
What's the size, material, and chain?
18 mm pendant in 925 sterling silver, nickel-free. 45 cm chain with a 5 cm extender. Ships free worldwide via DHL Express in 1-5 business days, with all import duties prepaid. Comes in a ready-to-gift jewelry box with the 30-day "Love It or Return It" policy.
Are there matching cell-type pieces in the catalog?
Yes. Macrophage, lymphocyte, neutrophil, and antibody necklaces all sit in the same immunology range. Several customers buy two or three together to mark a thesis defence or a new lab.
