Living cells are in constant motion. They move around,
change shape, divide and merge. Inside, a host of molecules
carry out their own complex movements in the name of the
cell. The proper orchestration of these cell and molecule
movements is critical for cell survival and function.
Activities including cell division, the relaying of nerve
impulses and pathogen discovery rely on the careful timing
and control of dynamic biochemical reactions within cells.
Tens of thousands of these events occur in living cells
every second, and new technologies are starting to show us
how, when and where these events occur.
The newly established Center for Cell Dynamics in
Development and Disease at Johns Hopkins brings together
experts across many disciplines to advance our
understanding of the control of biochemical reactions in
real time and space and further the available technologies
for them to happen.
To kick off this new multidisciplinary collaboration,
the center has invited leaders in the cell dynamics field
to present their latest findings at an all-day symposium on
Wednesday, May 2. Among the topics to be discussed are the
most recent developments in "biosensors" and live cell
imaging and how these techniques have furthered our basic
understanding of cell biology and immune and nervous system
The Center for Cell Dynamics Inaugural Symposium,
titled Molecules in Motion: The Art and Science of Cell
Dynamics, will be held from 8:15 a.m. to 6 p.m. in the
School of Medicine's Vernon B. Mountcastle Auditorium, East
Baltimore campus. More than 200 key scientists are expected
to attend the event to hear the following presentations:
Visualization of Immune Cell Activity Using 2-photon
Microscopy." Ronald Germain, deputy chief, Laboratory of
Immunology, and head, Lymphocyte Biology Section, National
Institutes of Health.
