Reviewed International journal C. Watanabe, G.L. Shu, N.V. Giltay, E. A. Clark Immunology and Cell Biology 1 - 11 2018.06 More details Authorship：Lead author Language：English Publishing type：Research paper (scientific journal) Publisher：Wiley The caspase (Casp) family of proteases regulate both lymphocyte apoptosis and activation. Here, we show that Casp6 regulates early B-cell development. One-week-old Casp6 knockout (Casp6 KO) mice have significantly more splenic B-cell subsets than wild-type (WT) mice. Adult Casp6 KO mice have normal levels of total splenic B cells but have increased numbers of B1a B cells and CD43+ "transitional" or splenic red pulp (RP) B cells. These results suggested that Casp6 may function to control B-cell numbers under nonhomeostatic conditions and during B-cell development. Consistent with this model, reconstitution of B cells was dysregulated in Casp6 KO mice after sublethal irradiation. Furthermore, bone marrow pro-B, pre-B and immature B-cell numbers were significantly higher in 1-week-old Casp6 KO mice than in 1-week-old WT mice. Casp6 KO pro-B cells proliferated more in response to IL-7 than WT pro-B cells, suggesting that Casp6 regulates early B-cell responses to IL-7. Indeed, adult and aged Casp6 KO mice had elevated numbers of IL-7αR+ Sca1+ precursors of common lymphoid progenitors, suggesting Casp6 may help regulate progenitors of B cells and early B-lineage cells. Casp6 regulates B-cell programs both during early development and after antigen stimulation in the periphery.

Reviewed International journal Akihiro Matsumoto, Chie Watanabe, Masahiro Murakami Drug Discoveries & Therapeutics 13 ( 6 ) 343 - 353 2019.12 More details Authorship：Second author Language：English Publishing type：Research paper (scientific journal) Publisher： International Advancement Center for Medicine & Health Research Co., Ltd. Conventional oral preparations generally release incorporated drugs omnidirectionally, including into the lumen, leading to a low bioavailability of drugs that are unstable in the gastrointestinal tract. Here, we designed Janus microspheres for efficient mucosal drug delivery as single-sided-release microspheres with the oriented attachment to mucus and evaluated their attachment to and orientation on a Caco-2 (human Caucasian colon adenocarcinoma cell line) monolayer. The microspheres comprised a mucus-oriented hemisphere of an ammonioalkyl methacrylate copolymer and a protective hemisphere of a hard fat. Fluorescein isothiocyanate-dextran with an average molecular weight of 3,000-5,000 Da (FD4) was used as a model hydrophilic drug. A water-in-oil emulsion-type solvent evaporation method was employed for fabrication of the Janus microspheres. The yield of Janus microspheres was found to be dependent on the polymer-to-hard fat ratio, with a maximum yield of over 90% being obtained at a ratio of 1:2, whereas lower and higher ratios resulted in monolithic or star-shaped microspheres. FD4 was specifically localized in the polymeric hemisphere. A cell culture study revealed that the Janus microspheres attached to a Caco-2 monolayer via their polymeric hemispheres with the hard fat hemisphere providing a protective sealing. This may lead to the development of an effective enteral drug delivery system for biomedicines, such as polypeptides and nucleic acids.

The production of conventional pharmaceutical preparations considering factors such as the oral and rectal dosage form is an essential step in the development of a wide range of oligonucleotide drugs. However, oligonucleotides are macromolecules that are easily disintegrated by nucleases and as such, are generally poorly absorbed by the intestine. We have recently developed a hepatocyte-specific delivery technique for oligonucleotides via an enteral route. The chemical conjugation of siRNA with alpha-tocopherol utilized chylomicrons, which acted as a specific in vivo carrier to the liver and were formulated as lipid nanoparticles using unsaturated fatty acid as an absorption enhancer. The method demonstrated effective silencing of the targeted mRNA (ApoB) expression in mice in a postprandial state (Murakami, et al, Sci. Rep. 2015). In this talk, we will provide an overview of the concept of our enteral delivery technique and discuss our recent results on the development of a DNA/RNA heteroduplex oligonucleotide (HDO) which was newly prepared as a more specific and potent oligonucleotide drug (Nishina K., et al. Nat. Commun., 2015). We used a tight junction (TJ) modulator as a para-cellular specific permeation enhancer (Takahashi A, et al., Biomaterials, 2012) and demonstrated that the HDO conjugate with alpha-tocopherol specifically delivered to the liver following rectal administration of the enema in mice and suppressed ApoB gene expression, consequently achieved the reduction of plasma triglyceride and cholesterol levels in the model mice with hypercholesterolemia. These findings suggest that our enteral delivery technique via the lymphatic route should be useful for developing a non-invasive conventional preparation for oligonucleotide therapeutics. Applicability of this technology to the other organ-specific oligonucleotide delivery systems using conjugates with different targeting molecules or ligands remains to be investigated.
