Relative and absolute numbers of E- and EAC-rosette-forming cells in lymphoid organs. 1977

R Pabst, and E Kaupp, and F Trepel

The percentage of lymphocytes of the blood and lymphoid organs of young pigs were determined by forming rosettes with pretreated sheep red blood cells (AET-rosettes) or with sheep red blood cells coated with antibody and complement (EAC-rosettes). The mean figures for AET-rosettes were 70% for the blood, 93% for the thymus, 78% for lymph-nodes and 68% for the spleen. For EAC-rosettes the numbers were 16%, 0%, 16% and 19% respectively. The absolute numbers of rosette-forming lymphocytes were estimated on the basis of previously determined numbers of lymphoid cells in young pigs. Even by excluding the data for the thymus, there would be about three times more AET-rosette forming lymphocytes than EAC-rosette forming cells in the whole animal. About 11% of all lymphocytes did not show any of these markers. Data on the numbers of "B" and "T" lymphocytes in human lymphoid organs from the literature were summarized and compared to those found in pigs and thus, the absolute numbers for a young adult man estimated.

UI MeSH Term Description Entries
D007104 Immune Adherence Reaction A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound C3 molecules on the C3b receptor sites of the indicator cell.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules.
