Biological response modifiers (BRMs) can alter interactions between the immune system and cancer cells to boost, direct, or restore the body's ability to fight disease. Mice with ethylnitrosourea- (ENU) induced leukemia were here used to monitor the therapeutic efficacy of lipopolysaccaride (LPS), Bacillus Calmette Guerin (BCG) and sheep erythrocytes (SRBC). Flow cytometry based CD34+ positivity analysis, clonogenicity, proliferation and ultrastructure studies using scanning electron microscopy (SEM) of stem cells in ENU induced animals with and without BRMs treatment were performed. BRMs improved the stem-stromal relationship structurally and functionally and might have potential for use as an adjunct in human stem cell therapy.

Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by progressive joint deterioration; Furthermore, RA can also affect body tissues, including the skin, eyes, lungs, heart and blood vessels. The early stages of RA can be difficult to diagnose because the signs and symptoms mimic those of many other diseases. It is not known exactly what triggers the onset of RA and how to cure the disease. But recent discoveries indicate that remission of symptoms is more likely when treatment begins early with strong medications known as disease-modifying anti-rheumatic drugs (DMARDs). Tumor necrosis factor (TNF) inhibitors are typical examples of biotherapies that have been developed for RA. The substances may occur naturally in the body or may be made in the laboratory. Other biological therapies care biological response modifiers (BRMs)such as monoclonal antibodies, interferon, interleukin-2 (IL-2) and a protein binder using repeat units. These substances play significant anti-inflammatory roles. Proteins with recurrent, conserved amino acid stretches mediate interactions among proteins for essential biological functions; for example, ankyrin (ANK), Heat repeat protein (HEAT), armadillo repeat protein (ARM) and tetratricopeptide repeats (TPR). Here, we describe Leucine rich repeats (LRR) that ideally fold together to form a solenoid protein domain and is more applicable to our current study than the previously mentioned examples. Although BRMs have limitations in terms of immunogenicity and effector functions, among other factors, in the context therapeutic use and for proteomics research, We has become clear that repeat-unit-derived binding proteins will increasingly be used in biotechnology and medicine.

To investigate the capacity of anti-inflammatory cytokines and biological response modifiers (BRMs) to induce IL-$1{\beta}$, IL-6, TNF-${\alpha}$ gene overexpression from mouse macrophages, we isolated the resident peritoneal macrophages from BALB/c mouse (8 week old) and incubated for 6 h with lipopolysaccaride (LPS) and Moschus moschiferus (MOMS) extracts. Analysis of inflammatory cytokines gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. 1. LPS and MOMS extract treatments resulted in a significant decrease in IL-$1{\beta}$, IL-6, TNF-${\alpha}$ mRNA expression level compared with the LPS treatment. 2. Among four sample of MOMS, Inhibitory effects of MOMS-A and MOMS-D for inflammatory cytokines gene expression were to be fine compared with the MOMS-Band MOMS-C. According to the above data, Because the anti- tumoral and anti-inflammatory response activities of macrophage are known to be dependent on the production of inflammatory cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) by macrophages, we suggest that evaluations of BRM for the reduction of inflammatory cytokines production by macrophages are important for clinical application.

Korean-style fermented soybean paste (KFSP), Doenjang, is a traditional food that is consumed as a protein source in Korea. Recently, efforts to identify biolgocial response modifiers (BRMs) have been focused on food products. Accordingly, this study which isolated abiologically active substance form KFSP, named KFSP-BRM, ws defined to be aheat-stable carbohydrate with a molecular weight of 2,000 kDa. The biological activity of KFSP-BRM was not inactivated by treatment with an anti-LPS antibody. The oral as well as intraperitoneal treatment of mice with KFSP-BRM significantly enhanced the number of B cells expressing surface significantly enhanced the number of B cells expressing surface immunoglobulins (IgM and IgG). Subsequently, an increased level of immunoglobulins in the sera was also observed. In vitro. KFSP-BRM was found to upregulate the production of interleukin-1 (IL-1) and IL-6 by mactro phages and B cells but not the production of IL-2 by T cells. In conclusion, these data demonstrate the presence of a BRM in KFSP, which may provide an additional benefit to those consuming it is a food. KFSP-BRM is a novel B cellmitogen distinct from fresh soybean lectin or B cell mitogens, such as LPS and Streptococcus protein A. The major biological effects of KFSP-BRM would appear to be anincreased production of IL-1 and IL-6 by macrophages and B cells, thereby enhancing the function of mature B cells.

담자균류의 버섯은 대부분 영양생장단계의 균사체와 포자를 형성하는 생식생장단계인 자실체로 나누어진다. 그러나 자연산 상황버섯은 자연계에서의 분포수가 극히 적어 그 자실체를 얻기 어려우며, 이러한 희귀성으로 인해 매우 고가로 거래되고 있다. 1990년대 중반 상황버섯은 균사체 배양기술과 인공재배법이 확립된 후 농가에서 대량생산되기 시작하였으며, 이에 따라 상황버섯의 유효성분을 이용한 기능성 식품 및 의약품의 개발이 활발하였다. 그러나 인공재배법에 의한 상황버섯 추출물은 자연산 추출물의 항암 및 효능면에서 차이를 나타내고 있어, 자연산 자실체와 같은 수준에서의 약효를 나타내기 위한 인공배양기술과 고농도 유효성분을 획득하기 위한 추출법이 핵심기술로 대두되었고, 인공배양된 상황버섯과 자연산의 다각도적인 약효 비교에 관한 연구가 아직까지 진행되고 있다. 따라서 상황버섯의 유효성분이 높게 함유된 저렴한 추출물이 생산될 수 있는 기반 기술들이 기능성 음료용수, 식품 및 의약품으로 개발에 중요한 핵심기술로 떠오르고 있다. 국내 상황버섯 기능성 식품의 시장은 상황버섯의 효능에 대한 인지 증대, 웰빙열풍을 의한 건강 음료에 대한 선호도 증대 등으로 인해 향후에도 10% 이상의 높은 성장률을 보일 것으로 예상된다. 현재는 중소기업들이 주로 활동하고 있어 마케팅 및 유통의 한계로 인해 시장이 크게 확대되고 있지 않으나, 사업매력도가 긍정적으로 평가되고 있어 대기업에서도 상황버섯을 이용한 기능성 식품 시장에의 진출을 모색하고 있다.
