Figure Legend Snippet: The TRPC5 antibody occludes the effect of FFA in hcrt/orx neurons. (A) Transient (2 min) bath-application of 100 µM flufenamic acid (FFA), a non specific blocker of cationic currents, produces a strong membrane hyperpolarization and cessation of firing; inset: in voltage-clamp this hyperpolarization corresponds to an outward current. (B) Voltage-clamp ramps in absence (Ctrl) and presence (FFA) of flufenamic acid. The subtraction of voltage-clamp ramps shown in the inset suggests the presence of a voltage-dependent cationic current. (C–D) In hcrt/orx neurons loaded with a TRPC5 antibody, bath-application of FFA had only a small additional effect either in current-clamp (C) or in voltage-clamp (D).
Figure Legend Snippet: Dual immunohistochemical staining for TRPC5 and hcrt/orx. (A–B) Photomicrographs from a dual-immunostained section combining an hcrt/orx antibody from Santa Cruz (A) and a TRPC5 antibody from Alomone Labs (B). Examples of double labelled hcrt/orx-TRPC5 cells are indicated by white arrowheads and one such cell by a double circle (enlarged in the corresponding small panels to the right). Some hcrt/orx cells do not express TRPC5, as shown by an example indicated with a single circle. It is noteworthy that many hcrt/orx-negative cells also expressed TRPC5, as shown by an example indicated with a downward arrow (in panels A and B). (C–D) Same as in A and B with an hcrt/orx antibody from Phoenix Pharmaceuticals (C) and a TRPC5 antibody from NeuroMab (D). (Scale bars: 20 µm).
Techniques Used: Immunohistochemistry, Staining
Figure Legend Snippet: The depolarized state of hcrt/orx neurons is blocked by a TRPC5 antibody. (A–C) In voltage-clamp configuration, intracellular application of either a TRPC1 (A) or a TRPC3 (B) or a TRPC4 (C) antibody (AbTRPC1, AbTRPC3 and AbTRPC4 respectively, all from Alomone Labs) has no effect on the current needed to clamp the cell at −50 mV. (D–E) Intracellular application of a TRPC5 antibody (Alomone Labs), in contrast, induces an outward current (D) that is blocked by co-application of a TRPC5 antigen (E). (F–G) In current-clamp configuration, intracellular application of a TRPC5 antibody alone (from either Alomone Labs (F) or NeuroMab (inset in F) induces an important membrane hyperpolarization and cessation of firing. In contrast, intracellular co-application of the TRPC5 antibody (Alomone Labs) together with its appropriate antigen (AgTRPC5) has no effect (G, to compare with F). (H) Voltage-clamp ramps in absence (Ctrl) and presence of a TRPC5 antibody (AbTRPC5, Alomone Labs). In the inset, subtraction of voltage-clamp ramps (Ctrl - AbTRPC5) suggests the presence of a voltage-dependent TRPC5 current.
