- Potential modulation on P-glycoprotein and CYP3A by soymilk and miso: In vivo and ex-vivo studies.
- Yu CP, Hsieh YW, Lin SP, Chi YC, Hariharan P, Chao PD, Hou YC.Author information School of Pharmacy, China Medical University, Taichung 404, Taiwan, ROC.AbstractP-glycoprotein (P-gp) and CYP3A4 both play very important roles in drug bioavailability, resistance and interactions. Our in vitro studies indicated that P-gp function was activated by many isoflavones. This study investigated the in vivo effects of soymilk and miso, isoflavone-rich soy foods, on P-gp and CYP3A by tracing the pharmacokinetics of cyclosporine (CSP), a probe drug of P-gp. Rats were orally administered CSP with and without soymilk or miso. A specific monoclonal fluorescence polarisation immunoassay was used to determine the blood concentration of CSP. The results showed that soymilk and miso significantly decreased the Cmax of CSP by 64.5% and 78.3%, and reduced the AUC0-540 by 64.9% and 78.3%, respectively. Mechanism studies revealed that the activities of P-gp and CYP3A4 were induced by soymilk and miso. In conclusion, ingestion of soymilk and miso significantly activated the functions of P-gp and CYP3A.

- CRAC channel inhibition produces greater anti-inflammatory effects than glucocorticoids in CD8 cells from COPD patients.
- Grundy S, Kaur M, Plumb J, Reynolds S, Hall S, House D, Begg M, Ray D, Singh D.Author information *University of Manchester NIHR Translational Research Facility, Manchester Academic Health Science Centre, University Hospital of South Manchester Foundation Trust, Manchester M23 9LT, U.K.AbstractThere are increased numbers of pulmonary CD8 lymphocytes in COPD (chronic obstructive pulmonary disease). CRAC (calcium release-activation calcium) channels play a central role in lymphocyte activation though the regulation of the transcription factor NFAT (nuclear factor of activated T-cells). We studied the expression of NFAT in lungs from COPD patients compared with controls, and evaluated the effects of CRAC channel inhibition compared with corticosteroids on NFAT activation and cytokine production in CD8 cells from COPD patients. The effects of the corticosteroid dexamethasone, the calcineurin inhibitor cyclosporin and the CRAC channel inhibitor Synta 66 were studied on cytokine production and NFAT activation using peripheral blood and isolated pulmonary CD8 cells. NFAT1 and CD8 co-expression in the lungs was compared in COPD patients and controls using combined immunohistochemistry and immunofluorescence. NFAT inhibition with either cyclosporin or Synta 66 resulted in significantly greater maximal inhibition of cytokines than dexamethasone in both peripheral blood and pulmonary CD8 cells [e.g. >95% inhibition of IFNγ (interferon γ) production from pulmonary CD8 cells using cyclosporin and Synta 66 compared with <50% using dexamethasone]. The absolute number of pulmonary CD8 cells co-expressing NFAT1 was significantly raised in lungs from COPD patients compared with controls, but the percentage of CD8 cells co-expressing NFAT1 was similar between COPD patients and controls (80.7% compared with 78.5% respectively, P=0.3). Inhibition of NFAT using the CRAC channel Synta 66 produces greater anti-inflammatory effects on CD8 cells from COPD patients than corticosteroids. NFAT is expressed at a high level in pulmonary CD8 cells in COPD.

- An update on drug-drug interactions with biologics for the treatment of moderate-to-severe psoriasis.
- Gupta R, Levin E, Wu JJ, Koo J, Liao W.Author information Keck School of Medicine of University of Southern California , Los Angeles, CA , USA.AbstractObjective: Moderate-to-severe psoriasis is a chronic skin condition that often requires systemic therapy and biologics are the newest systemic treatment available. A favorable aspect of biologics is that they are thought to have minimal risks for drug-drug interactions compared to oral systemic medications such as cyclosporine and methotrexate. However, this assumption has not been recently or adequately reviewed. We reviewed the literature to identify possible drug-drug interactions with biologics and other medications. Methods: We searched PubMed for published case reports, clinical studies, reviews, and Food and Drug Administration (FDA) labels discussing possible drug-drug interactions with biologics for the treatment of moderate-to-severe psoriasis. Results: There were only a small number of published articles describing drug-drug interactions with biologics. Our review identified two case reports, five clinical studies, and three pharmacokinetics reviews. The majority of articles did not observe clinically relevant drug-drug interactions with biologics. FDA labels do suggest a possible relationship between tumor necrosis factor (TNF)-alpha inhibitors and cytochrome P450 (CYP) activity. Conclusion: The paucity of information regarding drug-drug interactions reaffirms the idea that biologics have limited susceptibility to drug-drug interactions compared to other oral medications. Further studies are needed to adequately assess drug-drug interactions with biologics.
