  • Background: Multiple myeloma (MM) is influenced by genetic and micro-environmental changes. Malignant plasma cells produce an abnormal monoclonal immunoglobulin, as well as cytokines, such as IL-10 and IL-6 which stimulate cells of the bone marrow microenvironment (BMM) and cause dysfunction and failure of many organs. B cell activating factor (BAFF), IL6, IL10 are known to influence the growth & survival of the malignant clone. Aim: The objectives of the present study were to investigate the circulating levels of BAFF, IL-10 and IL-6, correlate them with well-known parameters of disease activity in patients with MM, and to detect their impact on the patients' survival. Materials and Methods: This study was conducted on 89 newly diagnosed MM patients and seventy apparently healthy volunteers as a normal control group. BAFF, IL6, IL10 were measured by ELISA for both groups. Survival analysis was performed for all patients. Results: Studied markers were higher in the MM patients compared to the normal control subjects. Patients' survival was improved by high serum BAFF levels. Conclusions: High levels of BAFF were found to improve patients' survival. BAFF and IL-6 can be considered probable diagnostic markers for MM.

  • Phage display technique as a new antibody production method can express the protein on the minor coat of phage particle in a library constructed by utilizing a recombination of genes coding the variable regions of immunoglobulin. This new method is particularly advantageous in producing antibodies against toxic substances and compounds with low immunogenicities. We first confirmed the concept of antibody expression on the phage particle by selecting a positive control of the phage library (e.g., Griffin.l donated from MRC center in England). The library was then employed to produce antibodies specific to human serum albumin via repetitive bio-panning procedure. The mean affinity of the antibodies selected gradually increased along with the number of bio-panning, which demonstrated that the phage display method could produce monocloanl antibodies with high affinities.

  • Hubakmawhang-tang (HMT), listed in Geumgweyoryak, is an oriental medicine used for the symptoms of asthma, such as cough and dyspnea. In this study, we investigated the HMT effects on ovalbumin-induced asthmatic in mice. We examined weight changes, airway hyperresponsiveness, histopathological abnormalities, immune cell infiltrations, immunoglobulin and inflammatory cytokine levels, and spleen body weight ratios in asthmatic mice. HMT inhibited airway hyperresponsiveness, immune cell infiltration, and airway remodeling and caused a significant lowering of serum IgE and IgG1 levels. The asthmatic mice had elevated IL-4 levels in lung tissue and this elevation was effectively prevented by HMT. HMT did not cause changes in body weight or in the spleen body weight ratio. Therefore, HMT might have an anti-asthmatic effect in the ovalbumin-induced mouse model.

  • Gastrodia elata Blume is a well-known kind of natural products used as a folk medicine for thousands of years. However, anti-atopic dermatitis-like effects of G. elata Blume had not been evaluated until now. The aim of the present study is to investigate the protective effects of water extract from the roots of G. elata Blume (GE) on 2, 4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions using balb/c mice. Combination treatment of GE (at a dose of 12.5 mg/kg body weight by administrated per os + 0.5 mg/cm2 as ointment to apply on ear and dorsal skin) was significantly inhibited spleen weight, ear thickness, levels of serum immunoglobulin E and number of mast cells, compared with that of 2, 4-dinitrochlorobenzene-included groups without GE. Furthermore, combination application by oral administration plus by ointment of GE significantly inhibited the histamine release from rat peritoneal mast cells. These results suggest that combination treatment of oral administration plus ointment form of GE could be helpful as a potentially natural pharmaceutical treatment on atopic-like dermatitis.

  • Understanding the developmental mechanisms of humoral immunity against intranasal antigens is essential for the development of therapeutic approaches against air-borne pathogens as well as allergen-induced pulmonary inflammation. Follicular helper T (Tfh) cells expressing CXCR5 are required for humoral immunity by providing IL-21 and ICOS costimulation to activated B cells. However, the regulation of Tfh cell responses against intranasal antigens remains unclear. Here, we found that the generation of Tfh cells and germinal center B cells in the bronchial lymph node against intranasal proteinase antigens was independent of $TGF-{\beta}$. In contrast, administration of STAT3 inhibitor STA-21 suppressed the generation of Tfh cells and germinal center B cells. Compared with wild-type OT-II T cells, STAT3-deficient OT-II T cells transferred into recipients lacking T cells not only showed significantly reduced frequency Tfh cells, but also induced diminished IgG as well as IgE specific for the intranasal antigens. Cotransfer study of wild-type OT-II and STAT3-deficient OT-II T cells revealed that the latter failed to differentiate into Tfh cells. These findings demonstrate that T cell-intrinsic STAT3 is required for the generation of Tfh cells to intranasal antigens and that targeting STAT3 might be an effective approach to ameliorate antibody-mediated pathology in the lung.

  • The storage stabilities of immunoliposomes incorporated with variable amounts of ganglioside $G_{M1}$ were investigated as a function of time. temperature. and composition by observing absorbance of visible light and calcein release. In the column chromatographe, the layer of unsaturated PE(dioleoylphosphatidylethanolamine : DOPE). unable to form stable liposomes at physiological temperature and pH, were formed when palmitoyl-immunoglobulin G(IgG) $(2.5{\times}10^{-4}\;mol/DOPE\;mol)$ added. The incorporation of ganglioside $G_{M1}$ into immunoliposome. enhanced the stabilities of bilayers during the extended period of storage. The turbidities of immunoliposomes coated with ganglioside $G_{M1}$ exhibited the maximum near 20 mol% $G_{M1}/DOPE$ mol. probably because of the disturbance of the bilayer characteristics, i.e., layer transition or reorientation of interaction sites. At low temperature. the higher stability was achieved than at elevated temperatures. After one week of storage. the redispersed liposomal solutions at lower temperatures maintained the original elution patterns in chromatography but broader distribution at elevated temperatures. During the storage, it is suggested the aggregation is the more dominant phenomena for liposomes kept at $5^{\circ}C$ than the fusion. while he fusion is at elevated temperatures.

  • Food allergy is defined as adverse reactions toward food mediated by aberrant immune mechanisms. Cow's milk allergy is one of the most common food allergies in childhood. This allergy is normally outgrown in the first year of life, however 15% of allergic children remain allergic. Cow's milk allergy seem to be associated with casein (${\alpha}_{s1}$-CN), ${\beta}$-lactoglobulin and whey protein. In addition to this, many other milk proteins are antigenic and capable of inducing immune responses. Various food processing affects the stability, structure and intermolecular interactions of cow milk proteins, as a result reduction the allergenic capacity. Heating, hydrolysis, chemical, proteolytic and other processes such as gamma-ray irradiation, high pressure, using probiotics treatments of milk to obtain hypoallergenic milk have been developed to reduce allergic reactions.

  • In this study, we investigated the effect of Phellinus baumii (PB) on immediate-type allergic reaction and inflammatory cytokine secretion. PB inhibited compound 48/80-induced systemic reactions in mice. PB inhibited compound 48/80-induced plasma histamine release. In addition, PB also inhibited the immunoglobulin (Ig) E-mediated local allergic reaction. Furthermore, PB decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis $factor-\alpha$ and interleukin-6 secretion in human mast cells. These results indicate that PB may be beneficial in the treatment of immediate-type allergic reactions.

  • The 94 KDa glucose-resulsted Protein (SH 94), one of stress Proteins, is a Ca2+-binding protein in the endoplasmic reticulum (ER). In this study, the possible effect of Ca2+ on the native conformation of grp 94 was examined. When the purified grp 94 was analyzed by Sel filtration in the presence of either EGTA or CaCl2, it was eluted with apparent molecular weight (MW) of 100 KDa in both cases. When similarly analyzed with microtome or cell Ivsate, however, srp 94 was eluted with apparent IW of 200 KDa in the presence of E6TA, while with apparent MW of 100 KDa in the presence of CaCl2, indicating possible association of grp 94 with one or more other proteins in the absence of CaCl2. Consequently, immunoprecipitation with anti-grp 94 was carried out to determine which proteins specifically interact with grp 94. It is sho%un that srp 94 may interact, in a Ca2+_dependent manner. with other proteins including BiP (grp 78) which is also a stress protein in the ER.
