Compartmentalization in cells is achieved by lipid membranes. Membrane fusion is an elementary biological event which comes in various forms.

The Case of the Noisy Neurons

The autho suggests that what appears as noise in the experiments are signals from other parts of the cortex—that is, noise is in the eye of the beholder.

Bronchospasm and its biophysical basis in airway smooth muscle

The topics addressed in this review are intended to highlight recent discoveries that bring airway biology and smooth muscle biophysics into the same arena once again.

Disentangling Sub-Millisecond Processes within an Auditory Transduction Chain

The authors presented a novel technique to disambiguate single processing steps within a larger sensory transduction sequence and to analyze their detailed temporal structures.

Surface dynamics in living acinar cells imaged by atomic force microscopy: Identification of plasma membrane structures involved in exocytosis

Their study suggests depressions to be the fusion pores identified earlier in mast cells by freeze-fracture electron microscopy and by electrophysiological measurements.

Fusion Pore in Live Cells

Recent studies using atomic force microscopy demonstrate for the first time the presence of the fusion pore and reveal its morphology and dynamics at near-nanometer resolution and in real time.

SNAREs in Opposing Bilayers Interact in a Circular Array to Form Conducting Pores

Three soluble N-ethylmaleimide-sensitive factor (NSF)-attachment protein receptors (SNAREs) have been implicated in membrane fusion.

Mechanical Forces Found To Exert Larger Role In Blood Vessel Health And Disease

Mechanical forces, including shear stress, stretch and pressure, can play unsuspected but equivalent roles in some aspects of cardiovascular health and disease.
