Cell-cell repulsion: Clues from the growth cone?

Cell, 1990
Since the classical studies of Holtfreter (1948), the generation and maintenance of tissue diversity during embryonic development have been explained on the basis of differential affinities between cells. More recently, it has been both reasonable and fashionable to describe such differences in terms of the selective expression of cell-cell adhesion ...

On-Cell MAS NMR: Physiological Clues from Living Cells

Journal of the American Chemical Society, 2012
While structural information on biomolecules is mainly obtained from purified in vitro samples, NMR can also be applied in the context of entire cells or organisms. The present study describes maturation processes in living Salmonella enterica serovar Typhimurium, a prevalent cause for human gastroenteritis.

Lethal clues to cancer-cell vulnerability

Nature, 2019
Cancer cells often have mutations in anticancer genes that make their survival dependent on other genes. The gene-editing approach CRISPR–Cas9 offers a way to identify such vulnerabilities. Cancer cells with microsatellite instability require WRN protein to survive.

New clues about T-cell antigen receptor complex function

Immunology Today, 1988
The emerging picture of the T-cell antigen receptor complex is that of an extraordinarily elaborate structure. The best-understood subunit is the Ti heterodimer, con- sisting of integral membrane glycoproteins bearing substantial structural and functional similarity to immunoglobulins 1. Somatic cell fusion and gene transfer experiments have shown that,

B-cell antigen receptor-induced apoptosis: looking for clues

Immunology Letters, 2005
Triggering of the B cell antigen receptor (BCR) can initiate divergent responses ranging from activation and cell division to apoptosis, depending on the differentiation stage and additional signals the cell receives. Despite considerable progress in unraveling general apoptosis pathways, the route from the BCR to apoptosis execution is still quite ...

Discrete epithelioid cells: Useful clue to Hodgkin's disease cytodiagnosis

Diagnostic Cytopathology, 2002
AbstractDiagnosis of Hodgkin's disease is made with more confidence than diagnosis of non‐Hodgkin's lymphoma on cytology. This study was undertaken to describe the presence of granulomas and a new cytologic feature, discrete epithelioid cells (DECs), in smears from Hodgkin's disease.

Cell migration in invertebrates: clues from border and distal tip cells

Current Opinion in Genetics & Development, 2001
Recent studies in two invertebrate systems, border cells in Drosophila melanogaster and distal tip cells in Caenorhabditis elegans, have provided important insight into the mechanisms of directed cell migration. These migrating cells are guided by extracellular signals, such as EGF, TGF-beta and netrin.

Heeding clues to giant cell arteritis

Postgraduate Medicine, 2004
To return to the case vignette, the new onset of headache in a 74-year-old woman with anemia and a markedly elevated ESR should alert the physician to the strong possibility of giant cell arteritis. Vision loss is the most significant potential early complication. Temporal artery biopsy is indicated, and treatment with corticosteroids should be started
