In mammals, the ankyrin ionotropic transient receptor potential type 1 (TRPA1) is the only member of the TRPA receptor gene subfamily. It is defined as a target for damaging and inflammatory effects in peripheral sensory neurons, which implies its functional role in the development of pain and neurogenic inflammation. Experimental studies indicate that calcium permeable non-selective ion receptor channel TRPA1 is activated by a number of exogenous irritant compounds, factors including low temperatures. This review describes the structure, properties, and physiological role of TRPA1 receptors.

Transient Receptor

Pain originating in inflammation is the most common pathologic pain condition encountered by the anesthesiologist whether in the context of surgery, its aftermath, or in the practice of pain medicine. Inflammatory agents, released as components of the body's response to peripheral tissue damage or disease, are now known to be collectively capable of activating transient receptor potential vanilloid type 1, transient receptor potential vanilloid type 4, transient receptor potential ankyrin type 1, and acid-sensing ion channels, whereas individual agents may activate only certain of these ion channels. These ionotropic receptors serve many physiologic functions-as, indeed, do many of the inflammagens released in the inflammatory process. Here, we introduce the reader to the role of these ionotropic receptors in mediating peripheral pain in response to inflammation.

To determine the role of the transient receptor potential vanilloid type 1 (TRPV1) channel in the regulation of renal inflammation, lipopolysaccharide (LPS, 3 mg/kg) was intraperitoneally injected into wild-type (WT) and TRPV1-null mutant (TRPV1−/−) mice. The kidney and serum were collected 6 or 24 h after LPS injection for morphological analysis and proinflammatory cytokine assay. LPS injection led to a similar degree of transient hypotension and bradycardia in WT and TRPV1−/− mice determined by a telemetry system. LPS administration caused parenchymal red blood cell congestion and fading of intact glomerular structure in TRPV1−/− compared with WT mice. Serum creatinine levels were higher 24 h after LPS injection in TRPV1−/− than in WT mice. Neutrophil and macrophage infiltration in the kidneys was greater 6 h for the former and 24 h for both after LPS injection in TRPV1−/− than in WT mice. Serum cytokine levels including tumor necrosis factor (TNF)-α, IL-1β, and IL-6 were higher 6 h after LPS injection in TRPV1−/− compared with WT mice. Likewise, renal chemokine levels including keratinocyte-derived chemokines and macrophage inflammatory protein were higher 6 h after LPS injection in TRPV1−/− than in WT mice. Renal VCAM-1 and ICAM-1 expression was further elevated 6 h for the former and 24 h for the latter after LPS injection in TRPV1−/− than in WT mice. Renal nuclear factor-κB (NF-κB) activity was further increased 6 h after LPS injection in TRPV1−/− compared with WT mice. Pharmacological blockade TRPV1 in WT mice showed aggravated renal and serum inflammatory responses resembling that of TRPV1−/− mice. Thus TRPV1 gene ablation exacerbates LPS-induced renal tissue and function injury, including aggravated renal neutrophil and macrophage infiltration, chemokine and adhesion molecule levels, and glomerular hypercellularity accompanying with further increased serum creatinine and cytokine levels. These results indicate that TRPV1 is activated during LPS challenge, which may constitute a protect mechanism against LPS-induced renal injury via reducing renal inflammatory responses.
