  • Patent number: 9156912
    Abstract: The object of the invention is to provide an immunological reconstitution promoter or a prophylactic agent for infections for use in allogeneic hematopoietic stem cell transplantation therapy for tumors. The promoter or prophylactic agent enables the amelioration of delayed immune reconstitution or the prevention of infection following transplantation, while maintaining the GVT effect of allogeneic hematopoietic stem cell transplantation. Specifically, in a transplant patient in whom immune reconstitution is delayed, such reconstitution can be promoted by administering, at an early stage following transplantation, a substance capable of depleting CD4+ cells. Early completion of infection management in the patient and improvement in the survival rate are anticipated as a result. In addition, the risk of complications associated with allogeneic hematopoietic stem cell transplantation is reduced, enabling more widespread use of this therapy.

    Abstract: An object of the present invention is to provide a preventive and/or therapeutic agent for radiation damage that has a novel mechanism of action and can prevent and alleviate a wide range of symptoms of radiation damage for which no therapeutic measures have been available so far, and moreover, is highly safe to humans. A preventive and/or therapeutic agent for radiation damage comprising a compound represented by the following formula (I) such as 5-aminolevulinic acid (5-ALA) or a salt thereof as an active ingredient can be used to improve the survival rate, improve body weight reduction, and alleviate hematopoietic disorder: (wherein R1 represents a hydrogen atom or an acyl group; and R2 represents a hydrogen atom, a linear or branched alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group).

  • Patent number: 7759066
    Abstract: Concerning intracellular signal transduction mechanism, there has been drawn a novel hypothesis that, even in the case where phosphorylation does not occur in the intracellular C-terminal domain of a receptor, an unknown molecule associates with the Pro-C terminal domain of a G protein-coupled receptor for each chemokine and thus leukocyte chemotaxis depending on the receptor is controlled. To examine this hypothesis and clarify therapeutic targets in inflammatory diseases as well as other various diseases, attempts are made to search for a CCR2-binding protein. As a result, a novel cytoplasmic protein associating directly and specifically with the Pro-12-C-terminal domain of CCR2 is found out and it is clarified that this protein forms clusters with CCR2 after stimulation with CCL2. Thus, it is confirmed that there is a novel signal transduction system in the G protein relating signal transduction in the CCL2-CCR2 pathway.

  • Publication number: 20100021442
    Abstract: Although the fields of therapeutic applications of dendritic cells are now expanding, dendritic cell precursors exist only in a small amount in the peripheral blood and, therefore, it is still difficult to obtain them in a therapeutically useful amount even though they are proliferated in vitro. Therefore, it is a key point in performing a therapy with the use of dendritic cells in practice to elevate dendritic cell precursor level in the peripheral blood of a patient. The present invention provides an agent for elevating dendritic cell precursor level in the blood which comprises an agonist to a receptor expressed in immature dendritic cells or a functional derivative thereof as the active ingredient.

  • Publication number: 20090117538
    Abstract: The present invention provides methods for providing as tags the nucleotide sequences at the 5? end of mRNA. The method of the present invention comprises the step of synthesizing cDNA using, as a template, mRNA whose CAP structure is linked with a IIs linker having a type IIs endonuclease recognition sequence. Tags including the nucleotide sequence from the 5? end of mRNA are generated by reacting the type IIs endonuclease to cDNA. Tags can be generated from all mRNA, independently of their nucleotide sequences. Methods for identifying transcriptional start sites and primers for full-length cDNA synthesis are provided based on the nucleotide sequence information of tags of the present invention.
