Abstract
The locus of the gene that codes for the antigen-specific suppressive T-cell factor was determined to be in a new subregion "I-J" which locates between I-B and I-C subregions in the H-2 histocompatibility complex. This was shown by two different lines of evidence: (a) The absorbing capacity for the suppressive T-cell factor of several alloantisera against restricted I subregions did not correlate with their specificity for previously known Ia molecules which are coded for by genes in I-A and I-C subregions, but was associated with the specificity for the products of genes putatively present between I-B and I-C subregions. By the occurrence of special recombinant strains, i.e. B10.A(5R), B10.A(3R), B10.S(9R), and B10.HTT, which differ with respect to the I-J subregion, we were able to produce alloantisera which distinguish I-J subregion gene products. The absorption studies using these special alloantisera directed to I-J subregion clearly indicated that the suppressive T-cell factor is a product of I-J subregion gene(s), and that the molecule is distinct from known Ia molecules expressed on splenic B cells. (b) Taking advantage of the fact that there is a strict histocompatibility requirement for the effective suppression between the donor and recipient strains of the suppressive T-cell factor, we were able to determine the required identities of the genes in the H-2 complex existing among those present between I-B and I-C. Again, utilizing the T-cell factors obtained from special recombinant strains, i.e. B10.A(4R) and B10.A(5R), we were able to locate the gene that codes for the suppressive T-cell factor reactive only with relevant haplotype strains between I-B and I-C subregions. These results are most reasonably explained by the presence of a new subregion I-J which is specialized in coding for the suppressive T-cell factor as a different molecule from previously known Ia molecules.

Abstract
The antigen-specific suppressive T-cell factor of mice, which had previously been shown to be an I region gene product, could effectively suppress the in vitro secondary antibody response of spleen cells from syngeneic or H-2 compatible mouse strains but not that of H-2 incompatible strains. The identities among genes in the left side half (K, I-A, and I-B) of the H-2 complex between the donor and recipient strains were found to be both necessary and sufficient for the induction of suppression. This suggests that the acceptor site for the suppressive T-cell factor is also determined by the gene present in the left side half of the H-2 complex. The cell type which expresses the acceptor site was found to be a subset of T cell. In general, the suppressive T-cell factor obtained from F1 mice could suppress the responses of both parental strains, and the parental factors could suppress the response of F1 mice. The results indicate that both suppressor and acceptor molecules are codominantly expressed on F1 T cells. There were found two types of defects in the expression of suppressor and acceptor molecules among mouse strains: A/J mice could not produce the suppressive T-cell factor despite that they could accept the factor produced by other H-2 compatible mouse strains. In contrast, all the B10 congeneic lines could produce the T-cell factor, but could not accept the factor produced by syngeneic and H-2 compatible non-B10 congeneic lines. The F1 hybrid of A/J and B10. A could both produce and accept the T-cell factor, and thus the expressions of suppressor and acceptor molecules were found to be dominant traits. These results indicate that the antigen-specific T-cell-mediated suppression is regulated by at least two genes both present in the H-2 complex, and that the complementation of these two genes is required for the induction of suppression.

Abstract
The phospholipid composition of rat small intestinal smooth muscle was investigated in comparison with those of the mucosa and liver. Phospholipid content per g of the wet smooth muscle was almost identical with that of the mucosa and was about 1/4 of that in the liver. The phospholipid/protein ratio of the smooth muscle was about 1/2 of the value in the liver. Sphingomyelin content was significantly high and amounted to 18% of total phospholipids. This value was about twice that in the mucosa and 4 times higher than that in the liver. On the other hand, the percent distribution of phosphatidylcholine was lowest in the smooth muscle. Distribution patterns of phosphatidylserine and phosphatidylinositol in the smooth muscle as well as in the mucosa were different from those in the liver. The occurrence of vinyl-ether and ether phospholipids was clearly demonstrated in the smooth muscle as well as in the mucosa. A major part of the ether lipids was detected in the phosphatidylethanolamine fraction, in which they amounted to about 50%; 40% as alkenyl-acyl type and 12% as alkyl-acyl type. A high content of ether lipids was also observed in the phosphatidylethanolamine fraction from mucosa, but the distribution was reversed, that is, 14% alkenyl-acyl type and 28% alkyl-acyl type. Fatty aldehydes, fatty alcohols, and fatty acids were also determined by gas-liquid chromatography. The compositions of fatty aldehydes in the phosphatidylethanolamine fraction from smooth muscle and from mucosa were similar, whereas the compositions of long chain fatty alcohol and fatty acids were clearly different. The compositions of fatty alcohols and fatty acids of the phosphatidylcholine fraction from smooth muscle showed significantly different patterns from those of the phosphatidylethanolamine fraction and from those of the same phospholipid fraction in the mucosa.

Abstract
Asakura, Taniguchi and Oosawa [1]proposed that muscle actin polymer under sonic vibration is in a different state from that of the ordinary double stranded helical structure (F-actin), characterised by partially interrupted structures of F-actin, a state of "f-actin". In order to confirm different states for actin polymers [1, 2], physicochemical studies were made by measurements of viscosity, flow birefringence, electric birefringence, fluorescence, electron microscopy, quasielastic light scattering and ATP splitting. The following results were obtained. (1) F-actin polymers can undergo two processes of depolymerization upon treatment with urea and various salts as judged by measurements of flow birefringence and viscosity: one is a rapid process in a solution containing K+ or Ca2+ and urea; the other is a slow process following a brief rapid one in a solution containing Mg2+ and urea. (2) In the presence of Mg2+ and a suitable concentration of urea, F-actin (FMU-actin) appeared to exhibit different properties than ordinary F-actin; it had lower viscosity and lower flow birefringence and it had on the whole a more flexible polymer structure, also judging from experiments of quasielastic light scattering, electric birefringence. The different structure was confirmed directly be electron microscopic observation. The aromatic side chains of FMU-actin were also more mobile than those of F-actin judging from fluorescence measurements. The transformation between F-actin and FMU-actin was reversible. (3) The state of FMU-actin polymers was also characterized by ATP splitting; FMU-actin split about one mole of ATP into ADP and inorganic phosphate per mole of actin monomer at room temperature, where F-actin did not. A molar excess of Mg2+ with respect to actin monomer at room temperature, where F-actin did not. A molar excess of Mg2+ with respect to actin monomer is required for ATP splitting. F-actin in solutions containing K+ or Ca2+ and urea did not split ATP. FMU-actin activated on Mg-ATP-ase of myosin at nearly the same rate as that of F-actin. (4) We have postulated a flexible filament model (f-actin). The relationships between the structure of f-actin and its functional role for force generation during contraction are discussed.

Abstract
An antigen-specific suppressive T cell factor, which was extracted from carrier-primed T cells, was further characterized in an in vitro secondary antibody response. The factor was capable of suppressing secondary IgG antibody response of primed spleen cells when it was added to the culture together with relevant antigen. The suppressive T cell factor was not released from primed T cells by a short-term culture with antigen, but was kept bound to the membrane of the residual cultured cells, only the physical disruption of which can release the T cell factor. The target of the suppressive T cell factor was determined as being the helper T cell, since the factor did not exert any effect in the absence of the helper T cell with identical specificity to that of the factor. The suppressive activity was completely absorbed with alloantisera specific for products of the I region of H-2 complex, although various anti-immunoglobulin antisera failed to do so. Close analysis of the specificity of alloantisera capable of absorbing the suppressor molecule indicated that the suppressive T cell factor may, in fact, be an I region gene product probably coded for by genes in I-A and/or I-B (including I-E) subregions.

Abstract
Newly weaned male rats were maintained on a riboflavin-free diet for 5 weeks, and a study was made on the effect of the deficiency upon liver lipids. The content of glyceride in the livers varied among the deficient rats. High contents of glyceride were demonstrated in one-third of the deficient rats, whereas the similar level as that of control was shown in the remaining deficient rats. Contents of phospholipids and relative amounts of individual phospholipids were not altered significantly by the deficiency. Riboflavin deficiency exerted effects on fatty acid components of liver lipids. The composition of fatty acids of triglycerides varied in the deficient rats depending on the content of glycerides. However trends of increase in linoleic acid and decrease in palmitic acid towards fatty liver were observed in the deficiency in comparison with the control. On the other hand, the changes in phospholipid fatty acids were similar in all deficient rats, and the increase in linoleic acid and the decrease in arachidonic acid were brought about by the deficiency compared with controls, respectively. In liver homogenates, the incorporation of 14C-palmitate into triglycerides was higher in the deficient rats irrespective of the presence or absence of fluorde but incorporation into phospholipids was slightly lower in the deficient rats than in control animals.

Abstract
Immunocompetent cell interactions are achieved via direct contact between functionally different cell types or via interactions between soluble factors elaborated by regulatory T cells and specific receptors on responding cells for the T cell factors. In either case, there exist certain restrictions with respect to the effective interactions, which depend on the state of differentiation and genetic background of the responding cell type. Such restrictions are considered to be mainly determined by the development and nature of the receptor site on responding cell types for different T cell factors, which is now refered to the "acceptor" for the T cell factors. The presence of such acceptor sites on different populations of both T and B cells has been demonstrated in various experimental systems, and they are now considered to be the site by which responding cells receive appropriate signal for destination of their further differentiation. We have tried to review the nature and possible role of acceptor sites on both B and T cells for different T cell factors with respect to the induction and regulation of immune responses. A special emphasis was put on the genetic nature of the acceptor site. The observed genetic restrictions in the acceptance of T cell factors by responding cells suggest that such restrictions are needed for meaningful and unmistakable communications between funcionally different immunocometent cells. Furthermore, the presence or absence of acceptor sites for certain T cell factors is supposed to be a very important factor for determination of the immune responsiveness of animals against certain antigens, and thus in some cases the Ir gene effect may predominantly affect the expression of acceptor site. Possible implications of acceptor site in the regulation of antibody response and in the network of immunocompetent cell interactions are discussed.

Abstract
Phospholipids in mitochondria can be exchanged with those in two microsomal fractions from rough endoplasmic reticulum (rough microsomes) and smooth endoplasmic reticulum (smooth microsomes) in vitro in the presence of cell supernatant. The amounts of phospholipids transferred from each submicrosomal fraction to nitochondria were slightly different. The compositions of the phospholipids transferred to mitochondria from both microsomal fractions were the same, though these two fractions actually had different phospholipid compositions.

Abstract
The measurement of the fluorescence intensity of tryptophan residues showed that a reversible transition in the local structure took place between 20 degrees C and 30c in intact virus particles and reconstituted protein assemblies of the ordinary strain and the tomato strain of tobacco mosaic virus. During this transition the overall polymer structure was maintained. In the case of the bean strain of tobacco mosaic virus, however, the fluorescence intensity did not show any transition in the same temperature range. Such a difference between different strains gave some information on the location of tryptophan residues possibly involved in the local structure change. The fluorescence polarization of intact virus particles showed no change in the whole temperature range, but the polarization of the reconstituted protein assembly of the ordinary strain showed a transition at the same temperature as the fluorescence intensity. This suggested a difference in the freedom of the local structure between intact virus particles and reconstituted protein assemblies. Oligomers of these virus proteins were stable up to 45c and above this temperature, began to make an irreversible transition where the secondary structure of the monomer was partially broken but the oligomer structure was retained.

Abstract
Rabbits thymectomized in early adulthood produced more antihapten antibody than sham-thymectomized controls after hyperimmunization with 2,4-dinitrophenyl bovine gamma globulin (DNP-BGG). The average associated constant of anti-DNP antibody produced by thymectomized animals was more than 10 times higher than that of the controls. Similar effects were obtained by extensive treatment of rabbits with antithymocyte serum (ATS) before and during the immunization with DNP-BGG. The results indicated that relative diminution of thymus-derived lymphocytes (T cells) resulted in a stimulation of antibody-forming cells with a higher affinity. On the other hand, preimmunization of rabbits with different doses of BGG caused either enhancement or suppression of the hapten-specific antibody response, depending on the priming dose of BGG. The suppressed antibody response was always associated with a marked decrease in the antibody affinity. If rabbits were partially tolerized with a large dose of soluble BGG, some of the animals produced little antibody against hapten (DNP) coupled to this carrier, and the affinity of produced antibody was low. However, other rabbits tolerized with BGG produced large amounts of anti-DNP antibody upon hyperimmunization with DNP-BGG, whose affinity was only slightly lower than that of the control. These results can be harmonized if it is assumed that the thymus plays an important role in the maturation of the immune response. It is postulated that T cells, in numbers ordinarily available, would first assist in the proliferation of antihapten antibody-forming cell precursors already selected by antigen, thus accounting for the rapid increase of antibody affinity in the early stage of immunization. However, after a larger number of carrier-specific T cells are made in response to continued immunization, these would suppress antibody-forming cells. The suppression would be greater for cells with higher affinity for antigen, resulting in a decrease in antibody affinity. This postulate explains preferential stimulation and suppression of cells having higher affinity receptors under circumstances in which T cell are relatively depleted or overstimulated, and further permits an explanation for the decrease of antibody affinity after long-term immunization.

Abstract
Ultraviolet flow dichroisms of tobacco mosaic virus (TMV), TMV-RNA and TMV-protein were measured using three strains of TMV. 1. Large positive dichroisms were observed with three strains of TMV, namely ordinary, bean form of bean, and tomato strains (TMV-OM, TMV-B and TMV-T, respectively) at about 255, 276, 284 and 290 nm. The positive dichroisms were confirmed with reconstituted protein assemblies of TMV-OM and TMV-B at about 276, 284 and 290 nm where tyrosine and tryptophan residues of these proteins contribute. These results show that the electronic transition moments of their base groups and aromatic groups are nearly parallel to the polymer axis. It is suggested that there is a strong interaction between the base groups of RNA and aromatic groups of amino acid residues in TMV. 2. A small negative dichroism was observed near 296-300 nm with intact TMV-OM and TMV-T and with the reconstituted protein polymer of TMV-OM. But negative dichroism was not observed either with the intact virus or the protein assembly of TMV-B. 3. Isolated RNA from TMV-OM, TMV-B and TMV-T showed no dichroism. The configuration of RNA in TMV appears to be imposed on it by its packing with the protein.
