TRP Channel Knockout Mice Lose Their Cool
نویسندگان
چکیده
Heat and cold transduction by peripheral sensory neurons is a fundamental step in the avoidance of dangerous thermal extremes. In this issue of Neuron, Dhaka et al. and Colburn et al. report that mice lacking the cold- and menthol-gated ion channel TRPM8 exhibit deficient behavioral responses to cold temperatures.

Hair-Cell Mechanotransduction Persists in TRP Channel Knockout Mice
Members of the TRP superfamily of ion channels mediate mechanosensation in some organisms, and have been suggested as candidates for the mechanotransduction channel in vertebrate hair cells. Some TRP channels can be ruled out based on lack of an inner ear phenotype in knockout animals or pore properties not similar to the hair-cell channel. Such studies have excluded Trpv4, Trpa1, Trpml3, Trpm1...
متن کاملMice lacking Homer 1 exhibit a skeletal myopathy characterized by abnormal transient receptor potential channel activity.
Transient receptor potential (TRP) channels are nonselective cation channels, several of which are expressed in striated muscle. Because the scaffolding protein Homer 1 has been implicated in TRP channel regulation, we hypothesized that Homer proteins play a significant role in skeletal muscle function. Mice lacking Homer 1 exhibited a myopathy characterized by decreased muscle fiber cross-sect...
متن کاملThe contribution of TRPC1, TRPC3, TRPC5 and TRPC6 to touch and hearing
Transient receptor potential channels have diverse roles in mechanosensation. Evidence is accumulating that members of the canonical subfamily of TRP channels (TRPC) are involved in touch and hearing. Characteristic features of TRP channels include their high structural homology and their propensity to form heteromeric complexes which suggests potential functional redundancy. We previously show...
متن کاملInternational Union of Basic and Clinical Pharmacology. LXXVI. Current progress in the mammalian TRP ion channel family.
Transient receptor potential (TRP) channels are a large family of ion channel proteins, surpassed in number in mammals only by voltage-gated potassium channels. TRP channels are activated and regulated through strikingly diverse mechanisms, making them suitable candidates for cellular sensors. They respond to environmental stimuli such as temperature, pH, osmolarity, pheromones, taste, and plan...
متن کاملH2-EB1 Molecule Alleviates Allergic Rhinitis Symptoms of H2-Eb1 Knockout Mice
Background: H2-EB1 molecule which is the homolog of Human HLA-DRB1 is proposed to be associated with allergic rhinitis (AR). Construction of H2-Eb1 knockout animal models provides a tool to elucidate the role of H2-EB1 and AR pathogenesis. Objective: To establish the H2-Eb1 knockout model and investigate the H2-EB1 functions in H2-Eb1 knockout mice as a model of AR. Methods: The Cre/Lox...
