Toll-like receptor 10

Toll-like receptor 10 is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Toll-like receptor 10 rather than just read about it. In short: Toll-like receptor 10 is a protein that in humans is encoded by the TLR10 gene. TLR10 has also been designated as CD290 (cluster of differentiation 290).

Reference excerpt

Toll-like receptor 10 is a protein that in humans is encoded by the TLR10 gene. TLR10 has also been designated as CD290 (cluster of differentiation 290). TLR10 has not been extensively studied because it is a pseudogene in mice, though all other mammalian species contain an intact copy of the TLR10 gene. Unlike other TLRs, TLR10 does not activate the immune system and has instead been shown to suppress inflammatory signaling on primary human cells. This makes TLR10 unique among the TLR family. TLR10 was thought to be an "orphan" receptor, however, recent studies have identified ligands for TLR10 and these include HIV-gp41. Ligands for TLR2 are potential ligands for TLR10.

Function The protein encoded by this gene is a member of the toll-like receptor (TLR) family which play a fundamental role in pathogen recognition and activation of innate immunity. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. TLR10 is unique among the TLR family in having an anti-inflammatory function, rather than a pro-inflammatory function. This was discovered by over-expressing TLR10 in human cell lines and using antibody-mediated engagement of the receptor on primary human cells. When TLR10 is activated in this manner, it suppresses the amount of cytokines produced, as compared to control cells. TLR10 engagement also has long-term effects on monocyte and B cell activation/differentiation by suppressing the transcription of activation markers. TLR10's mechanism of action is not yet known but activation of the receptor has been shown to suppress NF-κB, MAP kinase and Akt signaling events stimulated by TLR and CD40 ligands. The computational analysis reported that TLR10 can interact with peptidoglycan and (triacyl) lipopeptides in concert with TLR2 (as a heterodimer). Some ligands of TLR10 have been recently described: HIV-1 gp41, Helicobacter pylori LPS (TLR2/10), Listeria monocytogenes, B burgdorferi, H1N1/H5N1.

Expression TLR10 has been transcriptionally shown to be expressed in secondary lymphoid tissues such as the spleen, lymph nodes, and tonsils. More specifically, protein level expression of TLR10 has been shown on the surface of B cells, monocytes and neutrophils; but not on T cells. B cells have the highest expression of TLR10 among these cell types but the overall expression of TLR10 is low compared to other TLRs. TLR10 has also been shown to be produced intracellularly in monocytes and neutrophils. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene.

Worked examples

Example 1 — a first encounter with Toll-like receptor 10

Start with the simplest possible case. Write down what Toll-like receptor 10 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Toll-like receptor 10 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Toll-like receptor 10 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Toll-like receptor 10

In research: Toll-like receptor 10 appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Toll-like receptor 10 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Toll-like receptor 10 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clusters of differentiation, Genes on human chromosome 4, Human chromosome 4 gene stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Toll-like receptor 10 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
