Second Peak

The role of the thymus in the cyclical appearance of the dominant idiotype of the myeloma protein secreted by the TEPC-15 plasmacytoma (T-15)-bearing plaque-forming cells (PFC) and anti-idiotypic cells (i.e., cells with receptors for T-15) in the spleen during a primary response to the phosphorylcholine determinant of Streptococcus pneumoniae, strain R36a (Pn) was studied using normal mice, thymus-deficient nude mice, and thymus gland-grafted nude mice (TG-nude). The nude mice and their phenotypically normal littermates (LM) were backcrossed on the BALB/c genetic background. The kinetics of the anti-Pn PFC response of BALB/c inbred mice, littermates of nude mice, and TG-nude mice were essentially the same. There was an initial peak on day 5-6 followed by a decline to near background, and then a second peak on day 12. In nude mice, the first peak of anti-Pn PFC (day 5) was comparable in magnitude to that of mice with an intact thymus; however, there was no second peak. In contrast to the cellular response measured at the level of PFC, the serum antibody response to Pn (assayed by passive hemagglutination of sheep erythrocytes coated with Pn polysaccharide) was comparable in all groups of mice and did not show a measurable oscillation. The anti-idiotypic cellular activity was determined by the ability of spleen cells to bind radiolabeled (125I) TEPC-15 myeloma protein (IgA, kappa) which carries an idiotypic determinant indistinguishable from that of most anti-phosphorylcholine antibodies in BALB/c mice. Binding of radiolabeled McPC-603 (IgA, kappa) and MOPC-315 (IgA, lambda 2) myeloma proteins (which lack the T-15 idiotypic determinant) served as controls. The changes in T-15 binding by splenic lymphocytes following the Pn immunization differed between normal and athymic mice. BALB/c, LM, and TG-nude mice showed a biphasic pattern with peaks at days 3--4 and 10--11 that was nearly reciprocal to the PFC curve. On the other hand, T-15 binding in nude mice either declined and remained depressed or was not affected by the ongoing anti-Pn response. These observations demonstrate that mature T cells are required for cyclical idiotypic and anti-idiotypic responses to immunization with a T-independent antigen and suggest that the cyclical immune response may result from an interaction between idiotypic and anti-idiotypic cell clones.

An epithelial cell line, NPC/HK1, has recently been established from a biopsy specimen of a recurrent tumour of the nasopharynx which was histologically diagnosed as a moderately to well differentiated squamous cell carcinoma. A definite decrease in the amount of tonofilaments and desmosomes in the NPC/HK1 cells during the cell line establishment was observed. The present communication reports on the fine structures of the NPC/HK1 cells heterotraneplanted in athymic nude mice.

The purpose of this study was to demonstrate by ISH the presence of IL-8 mRNA, and by immunohistochemistry (IHC) the presence of the chemokine IL-8 and the distribution of infiltrating macrophages in subcutaneous melanomas in the same tumor. IL-8 is a multifunctional cytokine produced by melanoma cells, activated macrophages and monocytes and it has been shown to be a growth and angiogenic factor for tumor cells. More recently it was shown that constitutive expression of IL-8 correlated directly with metastatic potential of human melanoma cells in nude mice. IL-8 content of a solid tumor as determined by Western blot analysis does not take into account the contribution of macrophages. Previous studies showed that murine tumors contain many infiltrating cells interspersed among tumor cells whereas human tumors growing in nude mice exhibit macrophages at the periphery or between tumor islands. In this study we demonstrate the expression of IL-8 and the distribution of macrophages by immunoperoxidase assay and IL-8 mRNA by ISH.

Summary Aim: The purpose of this study was to assess the potential for radioimmunodetection (RAID) of murine anti-carcinoembryonic antigen (CEA) monoclonal antibody (MAb) F33-104 labeled with technetium-99m (99m-Tc) by a reduction-mediated labeling method. Methods: The binding capacity of 99m-Tc-labeled anti-CEA MAb F33-104 with CEA by means of in vitro procedures such as immunoradiometric assay and cell binding assay and the biodistribution of 99m-Tc-labeled anti-CEA MAb F33-104 in normal nude mice and nude mice bearing human colon adenocarcinoma LS180 tumor were investigated and compared with 99m-Tc-labeled anti-CEA MAb BW431/26. Results: The in vitro binding rate of 99m-Tc-labeled anti-CEA MAb F33-104 with CEA in solution and attached to the cell membrane was significantly higher than 99m-Tclabeled anti-CEA MAb BW431/261 (31.4 ± 0.95% vs. 11.9 ± 0.55% at 100 ng/mL of soluble CEA, 83.5 ± 2.84% vs. 54.0 ± 2.54% at 107 of LS 180 cells). In vivo, accumulation of 99m-Tc-labeled anti-CEA MAb F33-104 was higher at 18 h postinjection than 99m-Tc-labeled anti-CEA MAb BW431/26 (20.1 ± 3.50% ID/g vs. 14.4 ± 3.30% ID/g). 99m-Tcactivity in the kidneys of nude mice bearing tumor was higher at 18 h postinjection than at 3 h (12.8 ± 2.10% ID/g vs. 8.01 ± 2.40% ID/g of 99m-Tc-labeled anti-CEA MAb F33-104, 10.7 ± 1.70% ID/g vs. 8.10 ± 1.75% ID/g of 99m-Tc-labeled anti-CEA MAb BW431/26). Conclusion: 99m-Tc-labeled anti-CEA MAb F33-104 is a potential novel agent for RAID of recurrent colorectal cancer.
