Breaking ranks: how leukocytes react to developmental cues and tissue injury

Current Opinion in Genetics & Development

Abstract

Leukocytes are arguably the most motile cells in metazoans. Besides their well-described ability to migrate rapidly toward sites of tissue injury, tissue-specific macrophages migrate already during embryogenesis, when they take up residence in a wide range of organs. The recent identification of molecules responsible for the guidance of leukocytes during development and in response to injury has revealed that these modes of migration are under the control of surprisingly different signaling systems. While the developmental migrations are regulated by hard-wired pre-patterns of secreted proteins, the rapid acute response to injury involves signals like hydrogen peroxide or extracellular nucleotides such as ATP. Ongoing work aims to understand how these distinct signals are integrated in the cell to determine different cellular responses.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
