This review explores advances in our understanding of dynamicism in cellular signaling. Areas highlighted include the role of stochasticity in producing diversity in analogous signaling circumstances; population desynchronization's effect in masking newly appreciated repetitive bursts in protein phosphorylation and messenger RNA production; double ...

The osteocyte as a signaling cell
Physiological Reviews, 2022Osteocytes, former osteoblasts encapsulated by mineralized bone matrix, are far from being passive and metabolically inactive bone cells. Instead, osteocytes are multifunctional and dynamic cells capable of integrating hormonal and mechanical signals and transmitting them to effector cells in bone and in distant tissues.

Cell polarity is a fundamental entity of living organisms. Cells must receive accurate decisions where to divide and along which plane, along which axis to grow, where to grow structures like flagellum or filopodium and how to differentially respond to external stimuli.

Abstract In this article Jose Ales-Martinez and colleagues explore the role of Ig-associated molecules in providing isotype specificity to signals triggered by receptor crosslinking, focusing on possible differences between immature and mature B cells.

Abstract In plants, cells differentiate according to their position with relation to their cell neighbours. Monoclonal antibody (MAb) probes to polysaccharide epitopes, present at the surfaces of all plant cells, have defined a family of proteoglycan antigens which signify cellular position.

Cell–cell adhesion and signalling
Current Opinion in Cell Biology, 2002Signalling pathways activated by Rho small GTPases have recently been identified that coordinate junction assembly, stability and function, as well as interactions of adhesive complexes with the underlying cortical cytoskeleton. Particularly exciting is the interplay between adherens junctions, activation of Rho proteins and the dynamics of microtubule,

THE mating of the gametes of Ulva mutabilis1 occurs essentially as described for Chlamydomonas2,3 When the gametes are mixed, they cluster and agglutinate with the tips of their flagella. Pairs consisting of a (+) and (−)-gamete leave the cluster, the cell bodies are brought together and fusion initiated.
