Labarca, Pedro; Santi, Celia; Zapata, Otilia; Morales, Ezequiel; Beltrán, Carmen; Liévano, Arturo; Darszon, Alberto (Academic Press Inc., 1996)Ion channels are deeply involved in sperm physiology. In sea urchin sperm cyclic nucleotide levels increase during quimotaxis and in the acrosome reaction (AR). Although cyclic nucleotides are second messengers known to ...

Morales, Bernardo; Labarca, Pedro; Bacigalupo Vicuña, Juan (1995)In olfactory neurons from Caudiverbera caudiverbera, a mixture of putrid odorants trigger an inhibitory, K+-selective current and a hyperpolarizing receptor potential. The current-voltage relation resembles that of a ...

Gasque, Gabriel; Labarca, Pedro; Delgado Arriagada, Ricardo; Darzon, Alberto (WILEY-LISS, DIV JOHN WILEY & SONS, 2006-12)An important body of evidence documents the differential expression of ion channels in brains, suggesting they are essential to endow particular brain structures with specific physiological properties. Because of their ...

Labarca, Pedro; Bacigalupo Vicuña, Juan (Kluwer Academic Publishers-Plenum Publishers, 1988)The olfactory epithelium has the ability to respond to a large number of volatile compounds of small molecular weight. Ultimately, such a property lies on a specialized type of neuron, the olfactory receptor cell. In the ...

Labarca, Pedro; Wolff, Daniel; Soto, Ubaldo; Necochea, Cecilia; Leighton, Federico (Springer-Verlag, 1986)Fusion of a highly purified fraction of rat liver peroxisomal membranes to planar lipid bilayers incorporates large, cation-selective voltage-dependent pores. The PK/PCl ratio of these pores, estimated in KCl gradients, ...

Basso, Claudia; Labarca, Pedro; Stefani, Enrico; Alvarez, Osvaldo; Latorre, Ramón (1998)Shaker K+ channels inactivate through two distinct molecular mechanisms: N-type, which involves the N-terminal domain and C-type that appears to involve structural modifications at the external mouth of the channel. We ...

Delgado, Ricardo; Latorre, Ramón; Labarca, Pedro (1995)The selectivity and gating properties of cAMP-modulated, voltage-independent, K+-selective channel from Drosophila larval muscle were investigated using the patch-clamp technique. In symmetrical 115 mM K+ the channel ...

Delgado, Ricardo; Latorre, Ramón; Labarca, Pedro (1994)The two‐electrode voltage clamp technique was employed to measure end‐plate currents in larval neuromuscular junctions of wild‐type (Canton‐S) and of three different Drosophila Shaker mutants: ShakerKS133, Shaker102 and ...
