Dictyostelium: Evolution, Cell Biology, and the Development ...
This substance was named acrasin, a generic name for any chemotactic
molecule produced by a member of the order Acrasiales. In D. discoideum and a
number of other species, the acrasin is cAMP (Konijn et al., 1968), in P.
violaceum the ...

Princeton Alumni Weekly
We called the substance acrasin because the Latin name for the slime molds is
Acrasieae and even more to the point, there is a witch in Edmund Spenser's
Fairie Queene named Acrasia who attracted men and transformed them into
beasts.

Mathematical Problems in the Biological Sciences
The sensitivity to acrasin also increases a hundredfold at about the same time. I
shall present here the simplest of the models put forth to explain the onset of
aggregation, that due to my erstwhile colleagues Evelyn Keller and Lee Segel [5]

The Social Amoebae: The Biology of Cellular Slime Molds
4), and found that it only possessed one of the receptor proteins, one that was
only involved in internal developmental events; their acrasin is not cyclic AMP but
folic acid. This raised the reasonable idea that during the course of evolution ...

The Evolution of Complexity by Means of Natural Selection
Here all the amoebae are capable of giving off a chemical signal or attractant (
called an acrasin) which manages to guide the cells to central collection points
by chemotaxis. It is thought that after a period of starvation certain cells begin to ...

Qualitative Analysis of Nonlinear Elliptic Equations and ...
Aggregation of starved slime molds amoebae is mediated by a chemical
substance, so-called acrasin. The starved slime molds amoebae secrete acrasin.
At the same time the acrasin can be degraded by an extracellular enzyme which
has ...

Non-verbal Communication
Here communication takes place by means of the discharge of a chemical called
acrasin (Bonner, 1959). Acrasin, which may be more than one compound,
initiates release of further acrasin by other amoebae nearby, which sets up
centrifugal ...

Developmental Biology of Prokaryotes
The question is, how does a cell in a random array recognize aggregation
centres if the response is to an acrasin produced by all the cells in the population
(including itself)? Essentially there are two possible mechanisms. The first is
known as ...

Darwin's Biological Work: Some Aspects Reconsidered
Individual cells are attracted to the organizing centre by a chemical substance,
acrasin, which diffuses from it. Shafferm] demonstrated that, although the same
substance will attract the cells of more than one species, there is nevertheless a ...

Explosive Instabilities in Mechanics
They begin with a model with four constituents Cj which they denote by a(x,y,t),
the concentration of amoebae, p(x,y,t), the concentration of acrasin, rj(x,y,t), the
concentration of acrasinase, and c(x,y,t), the concentration of a chemical
produced ...
