How T cells communicate

Exploring how cells communicate.

How do injured cells communicate with the surviving cell monolayer?

Mechanically scratching cell monolayers relieves contact inhibition and induces surviving cells near the wound edge to move and proliferate. The present work was designed to test whether surviving cells passively respond to newly available space, or whether cells are actively stimulated by signals from injured cells nearby. We monitored intracellular free Ca2+ ([Ca2+]i) while scratching conflue...

How to communicate with vaccine-hesitant parents.

Development of safe and effective vaccines is one the greatest medical triumphs. However, despite high immunization rates in the United States, 85% of health care providers (HCPs) will have a parent refuse a vaccine for his or her child each year. HCPs have the greatest influence on a parent's decision to vaccinate his or her child. To effectively communicate with vaccine-hesitant parents, HCPs...

How to Communicate with Zillions of Robots

This paper discusses some communications issues relevant to a system consisting of an arbitrarily large number of simple autonomous robots, from several different perspectives: (a) in the language of traditional communications systems analysis, (b) by analogy with biological systems, and (c) as a problem of intelligent control and data fusion. Emphasis is placed on support for the system develo...

How to communicate smartly with your house?

We are involved in conceiving and implementing man–machine interfaces allowing multimodal and situated dialogue in order to interact with smart digital environments. Several methods are presented depending on how and what the user can say. We describe our approach and some tracks to permit to end-users to communicate more naturally with their house, by speech or by gesture, for instance. Some a...
