[EX Q]: Abstract: We have previously identified and described two distinct types of suppressor T cell factors specific for the PFC response to L-glutamic acid60-L-alanine30-L-tyrosine10 (GAT) or L-glutamic acid50-L-tyrosine50 (GT). Both of these factors are antigen-specific and I-J+. GAT-TsF1 is not MHC-restricted and is composed of a single polypeptide chain, whereas GAT-TsF2 is MHC-restricted and is composed of two different polypeptide chains. We have not previously found evidence for an obligatory, idiotype-specific suppressor T cell in this suppressor pathway. However, we now report that idiotype-specific suppressor T cells can be elicited by exposing normal spleen cells to GAT-TsF1 or GAT-TsF2 in the absence of antigen in vitro. These factor (TsF1/TsF2)-induced cells have been fused with the AKR thymoma, BW5147, and hybridomas were selected for production of suppressor factors that inhibit GAT-specific antibody responses in vitro. In this report, we characterize one monoclonal factor from each fusion. Neither factor binds GAT or the related co-polymer, GT; both factors have binding sites for GAT-specific idiotypes but not for unrelated idiotypes either in the form of antibody immobilized on Sepharose or as cell surface determinants expressed by B cell hybridomas. Moreover, their reactivities for a panel of monoclonal anti-GAT antibodies are overlapping but not identical. Both factors are composed of two polypeptide chains, and both chains are required for suppressive activity; one chain bears the I-J determinant, whereas the other possesses the idiotype-binding activity of the intact molecule. Both idiotype-binding factors are restricted by MHC- and Igh-linked genes, and transcomplementation is observed in the F1 mice between MHC-congenic and Igh-congenic parents. Both factors are active late in Mishell-Dutton cultures. These data support the contention that these two factors are similar but nonidentical members of an anti-idiotypic class of GAT-specific suppressor factors.

[EX Q]: Abstract: To determine factors involved in left ventricular aneurysm formation after transmural anterior myocardial infarction, 79 patients with a first myocardial infarction who underwent cardiac catheterization within 6 months of infarction were evaluated. Patients who had received thrombolytic therapy were excluded. Patients were divided into four groups depending on the status of the left anterior descending artery and the presence or absence of a left ventricular aneurysm: Group I (n = 25): aneurysm with occluded left anterior descending artery; Group II (n = 27): no aneurysm and occluded left anterior descending artery; Group III (n = 23): no aneurysm and patent left anterior descending artery; and Group IV (n = 4): aneurysm with patent left anterior descending artery. Single vessel disease was more common in Group I (aneurysm) compared with Groups II and III (no aneurysm) (chi 2(4) = 12.8; probability value equal to 0.012). Collateral blood supply in the presence of an occluded left anterior descending artery was significantly less in Group I (aneurysm) compared with Group II (no aneurysm) (0.9 versus 2.4, p less than 0.001). The extent of coronary artery disease and collateral blood supply in Groups I and II were directly related (p = 0.012). Neither age, sex nor risk factors for coronary disease correlated with aneurysm formation. At a mean follow-up of 48 months, no differences were observed in the incidence of recurrent angina, new myocardial infarction, embolic events or sudden death. More patients in Group II underwent coronary artery bypass surgery. Total occlusion of the left anterior descending artery in association with inherent poor collateral blood supply is a significant determinant of aneurysm formation after anterior myocardial infarction. Multivessel disease with either good collateral circulation or a patent left anterior descending artery is uncommonly associated with the development of left ventricular aneurysm.

[EX Q]: Abstract: Cow snout epidermal cells digested by 0.25% trypsin were separated into three regions of keratinocytes by Percoll density gradient centrifugation. The membrane fluidity of keratinocytes in each region was measured by electron spin resonance using 5-doxyl stearic acid (5-DSA) as a labeling agent. The order parameter(s) showed higher values as the depth of the epidermis decreased: lower region of epidermis, 0.632; upper region, 0.645; and horny cells, 0.680. These data indicated that membrane fluidity of epidermal cells decreased as cells approached the surface.
