The permeabilization of the mitochondrial outer membrane is an important and irreversible step in apoptosis. The point of no return occurs when Bcl-2 family proteins interact with the membrane to form pores and release toxic molecules into the cytosol of the cell. Addition of cholesterol to mitochondrial-like membranes has been shown to inhibit the pore formation process. The fact that the...

There currently exists only one mathematical model describing the course of a hepatitis C virus (HCV) infection in vitro: a non-spatial ODE model. However, experiments have shown that the spread of HCV infection has an important spatial component: infection disseminates both distally via release and diffusion of virus through the medium, and locally via direct, cell-to-cell infection. Both...

Cell division is a key step in the life of a bacterium. This process is carefully controlled and regulated so that the cellular machinery is equally partitioned into two daughter cells of equal size. In *E. coli*, this is accomplished, in part, by the Min protein system, in which Min proteins oscillate along the long axis of the rod-shaped cells. We have used high magnification, time-resolved...

Type IV pili (T4P) are very thin (5-8 nm in diameter) protein filaments that can be extended and retracted by certain classes of Gram-negative bacteria including *P. aeruginosa* [1]. These bacteria use T4P to move across viscous interfaces, referred to twitching motility. Twitching can occur for isolated cells or in a collective manner [2]. We have developed experimental and data analysis...

Defective interfering particles (DIPs) are imperfect virus which get spontaneously generated and amplified over the course of a viral infection. DIPs interfere with virus replication and suppress production of virus. Effective management of DIPs would be a boon to health technologies, such as vaccine production, where high viral yields are desirable. Furthermore, if their kinetics was...
