The aim of investigation is to define the peculiarities of immune system functioning of patients with endometrium cancer depending on the tumor differentiation grade. 133 female patients of comparable age in menopause have been examined: healthy women, patients with histological verified high-, medium- (1-st group) and low-differentiated (2-nd group) endometrium adenocarcinoma of the I stage. Estimation of the immune state has been made in accordance with generally accepted recommendations. Immune system activation has been stated in the 1-st group, in the 2-nd group there has been marked a dissociation of the function of basic immune system chains and a decrease of their functional abilities.

AbstractIn this paper, we review our work in the last 10 years wherein we examined the sulfides in the acetone extracts of garlic (Allium sativum), onion (A. cepa), and Welsh onion (A. fistulosum), obtained and characterized the structures of new sulfides, three 3,4-dimethylthiolane-type sulfides from onion and Welsh onion, respectively, and four acyclic-type, nine 3,4-dimethyl- thiolane-type, four 2-methylthiolane (and thiane)-type, two 1,2-dithiolane-type, and two 2-oxothiolane-type sulfides, together with (E)-ajoene and one kujounin-type sulfide from garlic. During this process, structural corrections were made in onionin A group, garlicnin A, and garlicnin B group in some 3,4-dimethylthiolane-type sulfides. Next, hypothetical pathways for the production of the aforementioned sulfides were proposed. Furthermore, it was revealed that a typical 3,4-dimethylthiolane-type sulfide, onionin A1 obtained from onion, having the isomeric structure of garlicnin B1 obtained from garlic, decreased tumor proliferation and controlled tumor metastasis. These results showed that onionin A1 is an effective agent for controlling tumors, and that the antitumor effects observed in vivo are likely caused by reversing the antitumor immune system. Activation of the antitumor immune system by onionin A1 might be an effective adjuvant therapy for patients with osteosarcoma, ovarian cancer and other malignant tumors.

Phosphocitrate (PC) inhibited calcium crystal-associated osteoarthritis (OA) in Hartley guinea pigs. However, the molecular mechanisms remain elusive. This study sought to determine PC targeted genes and the expression of select PC targeted genes in OA menisci to test hypothesis that PC exerts its disease modifying activity in part by reversing abnormal expressions of genes involved in OA. We found that PC downregulated the expression of numerous genes classified in immune response, inflammatory response, and angiogenesis, including chemokine (C-C motif) ligand 5, Fc fragment of IgG, low affinity IIIb receptor (FCGR3B), and leukocyte immunoglobulin-like receptor, subfamily B member 3 (LILRB3). In contrast, PC upregulated the expression of many genes classified in skeletal development, including collagen type II alpha1, fibroblast growth factor receptor 3 (FGFR3), and SRY- (sex determining region Y-) box 9 (SOX-9). Immunohistochemical examinations revealed higher levels of FCGR3B and LILRB3 and lower level of SOX-9 in OA menisci. These findings indicate that OA is a disease associated with immune system activation and decreased expression of SOX-9 gene in OA menisci. PC exerts its disease modifying activity on OA, at least in part, by targeting immune system activation and the production of extracellular matrix and selecting chondroprotective proteins.

Hypertension is associated with immune system activation and inflammation. Renal infiltration of both innate and adaptive immune cells contributes to injury, dysfunction, and increased blood pressure. Activated immune cells that exit blood vessels into the interstitium then travel through lymphatic vessels to draining lymph nodes where they signal to other immune cells to increase the immune response. It is unknown how renal lymphatic vessels change in the context of hypertension, immune system activation, inflammation, and injury. We hypothesized that renal macrophage infiltration, inflammation, and injury would significantly increase lymphangiogenesis in various strains of rats. SHR rats that exhibit hypertension and renal injury (SHR-A3 strain) had significantly increased numbers of renal lymphatic vessels at 40 weeks of age compared to WKY controls (total of 3 fields of view: 52 ± 1 vs. 28 ± 1; p<0.05). This was associated with increased renal macrophage infiltration. SHR rats that exhibit hypertension but minimal renal injury (SHR-B2 strain) had significantly less renal lymphatic vessel numbers compared to WKY controls (25 ± 2 vs. 28 ± 1; p<0.05) and normal levels of macrophages. The signals for lymphangiogenesis, VEGF-C and its receptor VEGF-R3, were both increased significantly at the protein level in the kidneys of SHR-A3 rats at 18 weeks but not different in the kidneys of SHR-B2 rats compared to WKY controls. To test whether the increased lymphangiogensis is due to hypertension and/or renal inflammation and injury, we obtained kidneys from Fischer 344 rats that exhibit normal blood pressure but develop renal inflammation and injury as they age. Compared to kidneys from control 4-month old Fischer rats, kidneys from 20-month and 24-month old Fischer rats had significantly increased numbers of lymphatic vessels (32 ± 3 vs. 74 ± 1 vs. 110 ± 6, respectively; p<0.05) and this was also associated with increased macrophage infiltration. Protein levels of VEGF-C and VEGF-R3 were increased significantly in 20-month old Fischer rats compared to 4-month old controls. These data together demonstrate that renal immune cell infiltration, inflammation, and injury increases lymphangiogenesis.
