[Abstract]:Background Psoriasis is a common and refractory chronic, inflammatory skin disease that affects about 2% of the world's population. It is characterized by erythematous scales. The main pathological changes are abnormal proliferation of keratinocytes, hyperkeratosis and incomplete keratosis, and infiltration of many inflammatory cells such as monocytes and lymphocytes. The pathogenesis of psoriasis is complicated. Immune dysfunction mediated by T lymphocyte subsets plays a key role in the occurrence and development of psoriasis. Studies have confirmed that the imbalance of Th1/Th2 cells is an important cause of psoriasis. In recent years, it has been found that two different T cell subsets, Th17 and Treg, play an important role in the pathogenesis of psoriasis. Stem cells (Stem Cell. SC) are human origin cells with the potential of self-replication and multi-differentiation. Ells, ASC, and embryonic stem cells (ESC), adult stem cells are undifferentiated cells, which exist in a differentiated tissue, have self-renewal and can specialize to form the cells that make up this type of tissue. Non-hematopoietic progenitor cells, derived from the mesoderm and widely distributed in bone marrow, fat, placenta, umbilical cord, epidermis and other tissues, can differentiate into a variety of mesoderm-derived cell lineages under specific induction conditions in vitro. They can not only differentiate into homozygotic skeleton, fat and chondrocytes, but also differentiate into endodermal nerves across the embryonic layer. Mesenchymal stem cells (MSCs) have special immunogenicity and strong immunomodulatory ability. They can secrete many cytokines to produce immunomodulatory effects on T lymphocytes. They can inhibit the activation, proliferation, differentiation and maturation of proinflammatory T lymphocytes and change immunity. The cytokines secreted by epidemic cells tend to resist inflammation and immune tolerance, and also promote the dominant differentiation of T lymphocytes that inhibit inflammation in order to help restore the immune balance of the body. It has been proved that mesenchymal stem cells have many similarities with kidney essence in origin, distribution and function, and stem cells have the properties of kidney essence. "Xuanfu depression, kidney essence deficiency" is the core pathogenesis of psoriasis proposed by Song Ping's research team on the basis of inheriting Zhu Renkang's academic ideas and achieving better clinical efficacy in the treatment of psoriasis. To open Xuanfu, invigorate the kidney and peel the yuan method of treatment, mainly in ephedra, Guizhi and other open Xuanfu drugs on the basis of adding Xianling spleen, Xianmao, Wellingxian, psoralea, mulberry parasitic, Eucommia ulmoides, Dipsacus, Cistanche deserticola and other invigorate the kidney and peel the yuan drugs, and achieved good results, but the specific mechanism is still unclear. Based on the theory and clinical practice of "opening Xuanfu and invigorating the kidney and peiyuan" in the treatment of psoriasis, and on the basis of summing up the previous work, a hypothesis was put forward for the first time to study the possible molecular mechanism of "opening Xuanfu and invigorating the kidney and peiyuan" in the treatment of psoriasis. In the upstream link of the disequilibrium of epidemic network, the abnormal immune regulation function of MSC in psoriasis patients is the key to the pathogenesis of psoriasis. Opening Xuanfu and invigorating kidney and Peiyuan can regulate the peripheral blood Th17 and Treg cells and secreted cytokines by interfering with the function of MSC. Flow cytometry, PCR, ELISA were used in this study. The biological characteristics and immune regulation function of AMSCs in psoriatic patients and healthy people were compared by bioinformatics techniques. The immune regulation effect of AMSCs on peripheral blood lymphocytes of patients with psoriasis was further studied. On this basis, the monomer of Herba Epimedii polysaccharides and Morinda officinalis polysaccharides were used as intervention means to surround the monomer on AMS. To explore the biological characteristics and immune regulation function of Cs in the treatment of psoriasis by using the theory of "opening Xuanfu, invigorating kidney and peiyuan" to guide the molecular mechanism of the clinical efficacy of psoriasis, verify the objectivity of the hypothesis, and explain its theoretical connotation, so as to provide a basis for the future treatment of psoriasis by "opening Xuanfu, invigorating kidney and peiyuan". The general biological characteristics and immunoregulatory function of adipose mesenchymal stem cells (AMSCs) from healthy volunteers and healthy volunteers were compared. 2. To study the immunoregulatory effect of AMSCs on peripheral blood lymphocyte (PBL) in patients with psoriasis. 3. To study the intervention of Morinda officinalis polysaccharide and Epimedium polysaccharide. The effect of AMSCs on the immune regulation of PBL in patients with psoriasis was studied in order to reveal the theoretical connotation of "opening Xuanfu, invigorating kidney and nourishing kidney and nourishing kidney and nourishing kidney and nourishing kidney and nourishing kidney and nourishing kidney and nourishing kidney and nourishing kidney". Phosphatase staining was used to identify the adipogenesis and osteogenic differentiation ability of AMSCs. PCR and ELISA were used to detect the expression or secretion of anti-inflammatory or pro-inflammatory factors in AMSCs from psoriatic patients and healthy people. 2. AMSCs from psoriatic patients and healthy people were added into PBL culture system respectively, and peripheral blood lymphocytes were cultured separately as control group. Treg and Th17 in PBL of psoriasis patients were detected by cytometry, and the expression or secretion of anti-inflammatory and pro-inflammatory factors in PBL of psoriasis patients were detected by PCR and ELISA. The biological characteristics of AMSCs in patients with psoriasis were detected by colorimetric assay, and the expression of anti-inflammatory and pro-inflammatory factors in patients with psoriasis were detected by PCR. The ratio of Treg and Th17 in PBL was detected by cytometry, and the expression or secretion of anti-inflammatory and pro-inflammatory factors in peripheral blood lymphocytes were detected by PCR and ELISA. 44 +, CD73 +, CD45 -, CD31 - and HLADR -. Moreover, all of them can differentiate into osteoblasts and adipocytes, but the proliferation of AMSCs in psoriasis group slowed down (p0.05), and the adipogenic differentiation ability was stronger than that in healthy control group. In addition, the expression or secretion of anti-inflammatory factors IL-10, IDO, TGF-beta in psoriasis patients were lower than that in healthy people (IL-10 p0.05, TGF-beta p0.01, IDOp 0.001), T-10. In the second part of the paper, the number of Treg lymphocytes in the AMSCs + PBL group was decreased (p0.01) and the expression and secretion of the nuclear transcription factors Foxp3 and IL-10 and TGF-beta in the Treg lymphocytes were decreased (p0.05) compared with those in the healthy subjects (p0.05). AMSCs in patients with psoriasis had no significant effect on the percentage of Th17 lymphocytes in peripheral blood compared with AMSCs in healthy volunteers. The inhibitory effect of AMSCs on the transcription factor RORgamt of Th17 lymphocytes and the secretion of pro-inflammatory factors from peripheral blood lymphocytes was weakened, but the results showed no statistical difference. Epimedium polysaccharide did not promote the proliferation of peripheral blood lymphocytes in psoriasis patients, but Morinda officinalis polysaccharide concentration was 28ug/ml, 56u. The effect of Morinda officinalis polysaccharide on the proliferation of peripheral blood lymphocytes in psoriasis patients was the most obvious (P 0.001) when the concentration of Morinda officinalis polysaccharide was 28 ug/ml. The concentration of MOP at 28 ug/ml was selected for further experimental study. It was found that Morinda officinalis polysaccharides had no effect on the phenotype, cycle, adipogenesis and osteogenic differentiation of AMSCs in psoriasis patients, but Morinda officinalis polysaccharides could enhance the immunosuppressive function of AMSCs in psoriasis patients, increase the mRNA expression of anti-inflammatory factors TGF-beta, IL-10, IDO and anti-inflammatory ligand PD-L1 and receptor TLR3. The results showed that Morinda officinalis polysaccharide could promote the increase of Treg in AMSCs of psoriasis patients compared with AMSCs+PBL in co-culture with PBL. At the same time, the expression or secretion of PBL anti-inflammatory factors TGF-beta and IL-10 were increased (TGF-beta P 0.05). Morinda officinalis polysaccharides had no effect on promoting the down-regulation of Th17 lymphocyte proportion in patients with psoriasis, but had weak effect on reducing the expression or secretion of IL-17 and IL-23 in peripheral blood lymphocyte. The ability of AMSCs to promote the proliferation of Treg lymphocytes in psoriatic patients was weaker than that in healthy people, and the ability of FoxP3, IL-10 and TGF-beta expression in peripheral blood lymphocytes was weaker. 3. Morinda officinalis polysaccharide could enhance the ability of AMSC in psoriatic patients. Meanwhile, AMSC s from Morinda officinalis after polysaccharide treatment can enhance the proliferation of Treg cells and the ability of AMSC s to secrete anti-inflammatory factors from peripheral blood lymphocytes. Therefore, Morinda officinalis polysaccharides can enhance the anti-inflammatory function of AMSC. 4. Molecular biology frontier technology was used in this study. This paper discusses the effect of Kidney-Tonifying and yuan-tonifying Chinese herbal monomer on the immunosuppressive function of psoriasis patients and the cellular and molecular mechanism of AMSCs on peripheral blood immune regulation.
