  • Therefore, ex vivo expansion of BMSCs is required to obtain a sufficient number of transplantable cells. Since BMSCs require several kinds of supportive factors for their growth, it is standard practice to use fetal bovine serum (FBS), while autologous human serum (HS) and pooled allogeneic HS have also been used. It has been suggested that FBS may not be favorable for clinical applications due to the possible risk of contamination (prions, viruses, zoonosis) or immunological reactions against xenogeneic serum antigens (Agata et al., 2009).

  • Harrison's Internal Medicine Chapter 116. Immunization Principles and Vaccine Use Principles of Immunization The immune system, composed of a variety of cell types and soluble factors, is geared toward the recognition of and response to "foreign" substances termed antigens. Vaccines convey antigens from living or killed microorganisms (or protein or carbohydrate molecules derived from these antigens) to elicit immune responses that are generally protective but can occasionally backfire and cause harm to the recipient.

  • Adipose tissue is an endocrine organ made up of adipocytes, various stro-mal cells, resident and infiltrating immune cells, and an extensive endo-thelial network. Adipose secretory products, collectively referred to as adipokines, have been identified as contributors to the negative conse-quences of adipose tissue expansion that include cardiovascular disease, diabetes and cancer.

  • Cystatin F is a recently discovered type II cystatin expressed almost exclu-sively in immune cells. It is present intracellularly in lysosome-like vesicles, which suggests a potential role in regulating papain-like cathepsins involved in antigen presentation. Therefore, interactions of cystatin F with several of its potential targets, cathepsins F, K, V, S, H, X and C, were studied in vitro. Cystatin F tightly inhibited cathepsins F, K and V with Ki values ranging from 0.17 nmto 0.35 nm, whereas cathepsins S and H were inhib-ited with 100-fold lower affinities (Ki 30 nm).

  • Cannabinoid receptors and their endogenous ligands, the endocannabinoids, have been detected in several blood immune cells, including monocytes/macrophages, basophils and lymphocytes. However, their presence in dendritic cells, which play a key role in the initiation and development of the immune response, has never been investigated.

  • There is a tightly regulated interaction, which is well-conserved in evolution, between the metabolic and immune systems that is deranged in states of over- or under-nutrition. Obesity, an energy-rich condition, is characterized by the activation of an inflammatory process in metaboli-cally active sites such as adipose tissue, liver and immune cells.

  • We have shown recently that in human T lymphocytes, leptin stimulates activity and expression of the endocan-nabinoid-degrading enzyme fatty acid amide hydrolase (FAAH), through STAT3 (signal transducer and activator of transcription 3) and its CRE (cAMP response element)-like transcriptional target in the FAAH promoter [Maccar-rone, M., Di Rienzo, M., Finazzi-Agro`,A., &Rossi,A. (2003) J. Biol. Chem. 278, 13318–13324]. We have also shown that progesterone, alone or additively with leptin, up-regulates theFAAHgene in human T-cells, through the Ikaros transcription factor [Maccarrone, M.

  • The book Cell Interaction focuses on various processes that occur within and outside the cells. Cell interactions are important for functioning of many organ systems: cell adhesion, tissue development, cellular communication, inflammation, tumor metastasis, and microbial infection. Key features include developmental cell interactions, immune and neural cell interactions, cell interactions in normal and disease conditions and advanced level methods to evaluate cell interactions.

  • It has long been noted anecdotally that affect, psychological state and neurologic state have influences on inflammatory skin diseases. Disorders such as psoriasis, atopic dermatitis, acne and rosacea, among many others, are reported to become exacerbated by stress. Furthermore, it is widely believed that stress alters cutaneous immunity. However, mechanisms responsible for these effects have remained incompletely understood. Scientific evidence for an influence of the nervous system on immune and inflammatory processes in the skin has been developed only relatively recently.

  • Harrison's Internal Medicine Chapter 105. Malignancies of Lymphoid Cells Malignancies of Lymphoid Cells: Introduction Malignancies of lymphoid cells range from the most indolent to the most aggressive human malignancies. These cancers arise from cells of the immune system at different stages of differentiation, resulting in a wide range of morphologic, immunologic, and clinical findings. Insights on the normal immune system have allowed a better understanding of these sometimes confusing disorders. Some malignancies of lymphoid cells almost always present as leukemia (i.e.

  • Heme oxygenase-1 catalyzes the breakdown of heme and is protective in models of kidney transplantation. In this study we describe the induction of heme oxygenase-1 mRNA and protein by insulin. Following treatment with insulin, a five-fold increase in heme oxygenase-1 mRNA and a four-fold increase in protein expression were observed in renal adenocarcinoma cells; insulin-induced heme oxygenase-1 expression was also demonstrated in mouse primary tubular epithelial cells.

  • Retinoids are potent immune modulators that inhibit Fas ligand (FasL) expression and thereby repress the activationinduced apoptosis of immature thymocytes and T-cell hybridomas. In this study, we demonstrate that all-transretinoic acid (all-trans-RA) directly represses the transcriptional activity of the nuclear factors of activated T-cells (NFAT), which is an important transactivator of the FasL promoter.
