Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Guilu Erxian Glue (GEG) and Danggui Buxue Tang (DBT) are traditional Chinese herbal formulas. According to the theory of traditional Chinese medicine, the combination of those two formulas (Modified Guilu Erxian Glue, MGEG) has the effects of tonifying the kidney and producing blood, was usually used to treat bone marrow failure diseases, including aplastic anemia (AA). AIM OF THE STUDY T lymphocytes play a crucial role in the disease pathogenesis and progression of AA. Our preliminary results confirmed that GEG can improve the damage of hematopoietic stem cells in mice, while DBT can reduce the proliferation and differentiation of T lymphocytes and inhibit the production of IFN-γ. We hypothesized that the combination of those two herbal formulas could inhibit immune attack and restore hematopoietic function through multiple mechanisms. In this study, we aim to study the curative effect of MGEG on regulating the expression of Signal lymphocyte activating molecule (SLAM), an activation-related molecule in T lymphocytes, thereby suppressing the immune function of T cells and decelerating the damage to hematopoietic stem cells. MATERIALS AND METHODS High-performance liquid chromatography-electrospray ionization/mass spectrometry system was used to identify the components of the MGEG formulation. Induction of aplastic anemia mouse model by injecting allogeneic lymphocyte suspension into BABL/c mice after ionizing radiation. Cyclosporine A (CsA) was used as a positive control drug. Flow cytometry was used to detect the number and apoptosis rate of hematopoietic stem cells in the bone marrow. Enzyme-linked immunosorbent assay was performed to measure the levels of IFN-γ and TNF-α. Immunofluorescence staining was used to assess the expression of T-bet and SLAM-SAP. Western Blot was conducted to examine the expression of activation-related molecules in T lymphocytes and proteins related to the Fas signal pathway. Hematoxylin-eosin staining was performed to observe pathological changes in the bone marrow tissue. Wright-Giemsa staining was utilized to evaluate alterations in the cellular composition and basic structure of the bone marrow cells (BMCs). Transmission electron microscopy was employed to observe changes in the structure and morphology of hematopoietic stem cells. The hematology analyzer was used to detect peripheral blood parameters. RESULTS Twenty-three different components were identified in MGEG. After MGEG treatment, the expression levels of Fyn and SLAM-SAP binding were increased in AA mice, while the expression levels of T-bet were decreased and the secretion of IFN-γ was reduced significantly. Additionally, MGEG also could downregulate the protein levels of Fas, caspase-3, and cleaved caspase-3 in AA mice. CONCLUSION MGEG could attenuate the production of IFN-γ by promoting the SLAM-SAP signal pathway to regulate the generation and distribution of T-bet in T cells. Additionally, it suppresses apoptosis of HSCs through intervention in the Fas-dependent pathway, thereby mitigating immune-mediated damage to HSCs.

Abstract
The present study aimed to explore the therapeutic effects of cyclosporin A (CsA) on spinal cord injury (SCI) in rats with hyperglycemia and to identify a novel potential method to treat SCI in the presence of hyperglycemia. Female Sprague‑Dawley (SD) rats were randomly allocated into four groups: Sham, SCI, SCI+hyperglycemia and SCI+hyperglycemia+CsA groups. Streptozotocin‑induced hyperglycemic SD rats and a weight‑drop contusion SCI model were established. The Basso, Beattie, Bresnahan scale and inclined plane test were used to evaluate the neurological function of the rats. Flow cytometric assay was performed to detect the apoptotic rates of cells in the spinal cord. ELISA and western blot analysis were performed to determine the levels of interleukin (IL)‑10, tumor necrosis factor (TNF)‑α, cyclophilin‑D (Cyp‑D) and apoptosis‑inducing factor (AIF). The results demonstrated that CsA significantly improved the neurological function of the SCI rats with hyperglycemia. CsA markedly reduced the number of apoptotic cells exaggerated by hyperglycemia in the spinal cord of the SCI rats. CsA significantly decreased the expression levels of IL‑10, TNF‑α, Cyp‑D and AIF in the spinal cord of the SCI rats. Overall, the present study revealed a significant role of CsA in the treatment of SCI in the presence of hyperglycemia by inhibiting the apoptosis of spinal cord cells.

In-vitro influence of mycophenolate mofetil (MMF) and Ciclosporin A (CsA) on cytokine induced killer (CIK) cell immunotherapy. J Transl Med 2016; 14:264. [PMID: 27620209 PMCID: PMC5020454 DOI: 10.1186/s12967-016-1024-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2016] [Accepted: 08/30/2016] [Indexed: 01/10/2023] Open
Abstract
Background Cytokine-induced-killer (CIK) cells are a promising immunotherapeutic approach for impending relapse following hematopoietic stem cell transplantation (HSCT). However, there is a high risk for treatment failure associated with severe graft versus host disease (GvHD) necessitating pharmaceutical intervention post-transplant. Whether immunosuppression with mycophenolate mofetil (MMF) or Ciclosporin A (CsA) influences the cytotoxic effect of CIK cell immunotherapy is still an open issue. Methods CIK cells were generated from PBMC as previously described followed by co-incubation with mycophenolic acid (MPA) or CsA. Proliferation, cytotoxicity and receptor expression were investigated following short- (24 h), intermediate- (3 days) and long-term (7 days) MPA incubation with the intention to simulate the in vivo situation when CIK cells were given to a patient with relevant MPA/CsA plasma levels. Results Short-term MPA treatment led to unchanged proliferation capacity and barely had any effect on viability and cytotoxic capability in vitro. The composition of CIK cells with respect to T-, NK-like T- and NK cells remained stable. Intermediate MPA treatment lacked effects on NKG2D, FasL and TRAIL receptor expression, while an influence on proliferation and viability was detectable. Furthermore, long-term treatment significantly impaired proliferation, restricted viability and drastically reduced migration-relevant receptors accompanied by an alteration in the CD4/CD8 ratio. CD3+CD56+ cells upregulated receptors relevant for CIK cell killing and migration, whereas T cells showed the most interference through significant reductions in receptor expression. Interestingly, CsA treatment had no significant influence on CIK cell viability and the cytotoxic potential against K562. Conclusions Our data indicate that if immunosuppressant therapy is indispensable, efficacy of CIK cells is maintained at least short-term, although more frequent dosing might be necessary.
