Abstract
Previous experiments have suggested that 3T3 cells were able to extend
pseudopodia toward latex particles up to 60 microns away from the cell body
if the particles were irradiated by an infrared beam in the range of 700-900
nm [Albrecht-Buehler, 1991: J. Cell Biol. 114:493-502]. The present article
reports that this response of cells to infrared light can be inhibited if
the cell center is simultaneously irradiated with a beam of the same light.
In marked contrast, the cells responded normally to the presence of infrared
light scattering particles if the second beam irradiated other parts of the
cell body. The results imply that the cellular mechanism of infrared
detection is located at the cell center. The infrared sensing mechanism
remains intact in enucleated cells and in cells which were incubated in
monensin to vesiculate their Golgi apparatus and inhibit their Golgi
functions. Accordingly, it is proposed that the centrosome which contains
the centrioles is the only remaining candidate in the cell center for a
cellular detection device for the direction of infrared signal sources. The
results support an earlier suggestion that centrioles may be such detection
devices [Albrecht-Buehler, 1981: Cell Motil. Cytoskeleton 1:237-245].
