What roles do regulatory T cells play in the control of the adaptive immune response?

Author(s) : Cohn, Melvin
Description : The immune system, like many systems responsive to specific stimuli, requires feedback regulation. The key regulatory element determining antigen-specific responsiveness is the effector T helper. As the response tends to overshoot, a feedback control of the magnitude of the response is critical to a...

THE USE OF BACTERIAL LIPOPOLYSACCHARIDES TO SHOW THAT TWO SIGNALS ARE REQUIRED FOR THE INDUCTION OF ANTIBODY SYNTHESIS

Author(s) : Watson, James , Trenkner, Ekkhart , Cohn, Melvin
Description : Evidence is presented that antigen-sensitive cells require two signals for induction. Normally these two signals are delivered to the cell via the recognition of two determinants on the immunogen: the first the receptor on the antigen-sensitive cell, and the second by the cooperating cell system. T...

Leukemia Viruses Associated with Mouse Myeloma Cells*

Author(s) : Watson, J. , Ralph, P. , Sarkar, S. , Cohn, Melvin
Description : Myeloma cells derived from BALB/c and C3H mice show evidence of infection by a murine leumemia virus. The immunoglobulin-producing myelomas secrete an RNA-containing virus with a density of 1.20 to 1.22 gm/cm3. RNA with a sedimentation coefficient of 74 S in 0.1 M sodium sodium chloride has been iso...

In vitro DIFFERENTIATION OF A MOUSE NEUROBLASTOMA*

Author(s) : Schubert, David , Humphreys, Susie , Baroni, Carlo , Cohn, Melvin
Description : Mouse tumor C1300 has been established in tissue culture. The cells have a round cell morphology in both the subcutaneous tumor and in suspension culture. However, when given a surface on which to attach, they send out processes up to 3 mm in length and assume the morphology of mature neurons. The a...

A NEW MOUSE IMMUNOGLOBULIN: IGG3

Author(s) : Grey, Howard M. , Hirst, Judith Wegman , Cohn, Melvin
Description : A new subclass of mouse IgG for which we propose the name IgG3 has been shown to have a mol wt of 150,000 consistent with an L2H2 structure, and is present in normal mouse serum at a concentration of 0.1–0.2 mg/ml. Its molecular weight, low carbohydrate content, glycopeptide analysis, and C-termina...
