Annual Review of Immunology, 2004
Naturally occurring CD4+ regulatory T cells, the majority of which express CD25, are engaged in dominant control of self-reactive T cells, contributing to the maintenance of immunologic self-tolerance.

In formulating Cell Theory, Schleiden(1) wrote in 1838: “Every higher organism is an aggregate of fully circumscribed and self-contained unit beings, the cells.” This basic tenet has been extraordinarily fruitful and influential in biology and medicine, and in many aspects its usefulness continues unabated.

Follicular helper CD4 T cells (TFH).
Annual Review of Immunology, 2011T cell help to B cells is a fundamental aspect of adaptive immunity and the generation of immunological memory. Follicular helper CD4 T (T(FH)) cells are the specialized providers of B cell help.

Cells interact not only with each other, but also with the extracellular matrix, which consists of proteoglycan, collagen, elastin, and multiadhesive proteins such as laminin. Both cell/cell and cell/matrix interactions require cell adhesion molecules, some of which occur in cell junctions.

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.

Cell length, cell growth and cell division
Nature, 1976When 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, 1991Dog 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, 1987In 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 ...

Cell-cell crosstalk between fat cells and immune cells
American Journal of Physiology-Endocrinology and MetabolismObesity 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 ...

Biomechanics of virus-to-cell and cell-to-cell fusion
Journal of Biomedical Engineering, 1984A 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.
