Cell-cell recognition

Trends in Biochemical Sciences, 1976
Abstract Several approaches in a variety of biological systems are being used in an attempt to understand cellular recognition at the chemical level. The precise molecular events in cell recognition have not yet been established.

Two types of murine helper T cell clone. I. Definition according to profiles of lymphokine activities and secreted proteins.

Journal of Immunology, 1986
A panel of antigen-specific mouse helper T cell clones was characterized according to patterns of lymphokine activity production, and two types of T cell were distinguished. Type 1 T helper cells (TH1) produced IL 2, interferon-gamma, GM-CSF, and IL 3 in

Cell length, cell growth and cell division

Nature, 1976
When cells of E. coli reach a certain critical length, which is constant in all growth conditions and eqqal to twice the minimum cell length, they abruptly increase their rate of elongation and divide about 20 min later. Chromosome replication terminates at about this same cell length but is not the signal for the change in rate of cell elongation.

Mast Cells and Cell-to-Cell Interactions in Airways

American Review of Respiratory Disease, 1991
Dog mastocytomas (anatomic and biochemical features comparable to normal dog and human mast cells) were used to study actions of mast cell mediators on several airway effector systems. We showed mastocytoma cell adherence to both cultured tracheal epithelial cells and tracheal tissue sections for greater than 48 h that was abolished completely by ...

Cell-Cell Interactions in the Testis*

Endocrine Reviews, 1987
In conclusion, the information available indicates that the interactions between different cell types in the testis play an important role in the control and maintenance of testicular functions. Further characterization of these interactions will clearly provide insight into the cell biology of the testis and into the regulation of cellular ...

Biomechanics of virus-to-cell and cell-to-cell fusion

Journal of Biomedical Engineering, 1984
A biomechanical model of virus-to-cell and cell-to-cell fusion is presented. Virus and the cells are modelled as initially spherical membranes of nonlinear elastic material that undergo large deformations. The membranes are connected by a cytoplasmic bridge which expands, resulting in the formation of a larger single sphere.

Cell-cell crosstalk between fat cells and immune cells

American Journal of Physiology-Endocrinology and Metabolism
Obesity is a metabolic disorder with pandemic-like implications, lacking viable pharmaceutical treatments currently. Thermogenic adipose tissues, including brown and beige adipose tissues, play an essential role in regulating systemic energy homeostasis and have emerged as appealing therapeutic targets for the treatment of obesity and obesity-related ...

Assaying Cell–Cell Adhesion

2006
A major feature in Dictyostelium development is the transition from the unicellular to the multicellular stage, a process brought about by chemotaxis and cell-cell adhesion. Growth-phase cells are weakly cohesive, whereas aggregation-competent cells adhere strongly to each other.
