potential relationships between amino acid motifs in the antigen binding groove of various alleles of the bovine major histocompatibility complex dr (bola-dr) molecule and peripheral blood mononuclear cell (pbmc) proliferation, in response to s. aureus and phytohemaglutinin, were investigated. the animals included in the study were approximately of the same age and comprised of pure holstein-fr...
Background: Dental Pulp Stem Cells (DPSCs) are multipotent mesenchymal stem cells. DPSCs can renew themselves and differentiate into various cell types such as adipocytes, osteocytes, neurons, etc. DPSCs possess immunomodulatory properties and can inhibit peripheral blood mononuclear cell (PBMC) proliferation. Recent studies showed that conditioned-medium mesenchymal stem cells also had immunos...
Immune responses of individuals infected with filarial nematodes are characterized by a marked cellular hyporesponsiveness and a shift of the cytokine balance toward a Th2/Th3 response. This modulation of cellular immune responses is considered as an important mechanism to avoid inflammatory immune responses that could eliminate the parasites. We investigated the immunomodulatory potential of a...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
Mesenchymal stem cells (MSCs) are multipotent progenitor that reported to be immune-privileged and immune-evasive. MSCs capable of differentiating into specific cell types for subsequent use in cell-based therapy. They express low levels human leucocyte antigen (HLA)-ABC no HLA-DR. Wharton’s jelly-derived (WJ-MSCs) were also found leukocyte G (HLA-G), which renders them immunosuppressive. This ...
Granulomatous inflammation around parasite eggs is the prominent lesion in human schistosomiasis. Studies have suggested the involvement of a series of suppressive mechanisms in the control of this reaction, such as macrophages, cytokines, idiotypic interactions and immune complexes (IC). The studies examine the role of IC obtained from chronic intestinal schistosomiasis patients (ISP) in the r...
In experimental murine cutaneous leishmaniasis, the purified Leishmania pifanoi amastigote protein P-4 has been shown to induce significant protection against infection. Further, recent studies examining the response of peripheral blood mononuclear cells (PBMC) from Leishmania braziliensis-infected human patients have demonstrated that the P-4 protein selectively elicits a significant TH1-like ...
BACKGROUND CD8+ T suppressor cells may play a role in immunoregulation. Recent studies have characterized this population by the lack of the CD28 molecule. These CD8+CD28 T cells differ phenotypically and functionally from CD8 + CD28 + T cells. Little is known about CD8 + CD28 cells in atopy. Our aim was to analyze the phenotype and functional properties of CD8 + CD28T cells in atopic and non-a...
background: the appendix is considered as part of the gut-associated lymphoid tissue; however, lymphocyte subsets in this tissue are not fully defined. objective: to investigate and compare the function and phenotype of lymphocyte subsets in peripheral blood and appendix of patients with normal and inflamed appendix tissues. methods: peripheral blood samples and appendiceal mononuclear cells we...
Background: Polycystic Ovarian Syndrome (PCOS) is a pro-inflammatory condition that supports the development of metabolic aberration and ovarian dysfunction. Chronic inflammation and the increased levels of androgens in this group of patients and their impact on the immune system may increase the risk of developing malignancies, including ovarian cancer. Thus, we interacted ovarian tumor cells ...
