Rosette formation between human lymphocytes and sheep erythrocytes. Inhibition of rosette formation by specific glycopeptides.
Rosette formation with unsensitized sheep erythrocytes is a characteristic of human thymus dependent lymphocytes. Release of glycopeptides from the sheep erythrocyte by trypsin reduces rosette formation. These tryptic glycopeptides inhibit rosette formation by untrypsinized sheep erythrocytes; this suggests that rosetting is mediated by erythrocyte surface glycopeptides. To investigate the mole...
متن کاملRosette formation by circulating lymphocytes from rheumatoid and nonrheumatoid subjects.
In the majority of patients with rheumatoid arthritis the immune response is most readily detected as a production of rheumatoid factors, IgM antibodies, which agglutinate to high titre erythrocytes coated with IgG antibodies from man, rabbit, or sheep, etc. Generally, only low titres of rheumatoid factors are found in nonrheumatoid individuals. Bach, Delrieu, and Delbarre (1970a, b) described ...
متن کاملRosette formation by peripheral blood lymphocytes in rheumatoid arthritis.
Rosette formation, a phenomenon in which a leucocyte becomes surrounded by a cluster of erythrocytes (Fig. 1) may occur in a variety of circumstances. For example, when lymphocytes from an animal which has been immunized against erythrocytes of another species are mixed with a suspension of the foreign red cells, a certain proportion of the lymphocytes will form rosettes (Biozzi, Stiffel, Mouto...

clonotype appeared at weeks 15-16 (tracks B2 and C3) and then died away. Rats D and E had biclonal spectrotypes at weeks 12 and 16, respectively (tracks D3 and E4). The acidic clonotype of rat E was replaced by a new one at 27 weeks (track E6). Similar changes occurred in the spectrotype of rat F, a dominant group of basic bands appearing at 20 weeks (track F5) to be replaced in turn by a clono...

which is empty during surgery hours apart from the surgery section. The women with cystitis were instructed to use the male urinal, urinating in an erect position separating the labia, and observing the stream. The use of the male urinal avoided fears of urinating over the edge of the bowl and enabled the patient to observe her stream in seclusion. Twenty-eight patients who were unable to aim a...
