Immunomodulating Actions of PSP

PsP, the protein-bound polysaccharide, extracted from a strain of Coriolus versicolor (Cov-1) by Professor Qing-yao Yang, has been proved to be effective against tumor both in animal experiments and in clinical patients. Previous results suggested that the antitumor effects of PsP were related to the potentiation of immunological responses, especially T-cell mediated immune responses of tumorbearing hosts. Since T-lymphocytes play an important role in immune response and T-cell deficiency existed in many diseases, the most noticeable one at present time is the acquired immune deficient syndrome (AIDS) which leads to the failure of T-cell functions and death. Until now there is no any
effective drug in curing this disease. It is of great interest to investigate if PsP can potentiate T-cell functions and restore the immune deficient conditions in tumor, AIDS and other viral infections. In this paper both in vivo and in vitro experiments were used to study PsP on: 1) immune organ weights, 2) antibody informations, 3) serum complement contents, 4) T lymphocyte proliferations, 5) interleukin-2 production, 6) delayed type hypersensitivity reaction, 7) phagocytic ability of reticulo-endothelial system and 8) protection of liver injuries from CCl4 intoxication.[…]

PSP, Coriolus Polysaccharide: Intra-Cellular Mycelia Extract of Coriolus Versicolor

As the leader in standardized mushroom extracts we believe passionately in sharing information from the growing body of published research on medicinal mushrooms. This is for education purposes only and MYCOPHARMA® cannot and does not vouch for the accuracy of independent research. To make your own informed decisions please refer to the original published research about Coriolus Versicolor.{…}

The Preliminary Appraisal of Polysaccharide Peptide (PSP) in Malignant and Non-malignant Diseases

So far no adverse drug reaction has been observed, there were no impairment of liver and renal functions after the long term administration of PSP even up to years.[…]

Trametes versicolor – Wikipedia, the free encyclopedia

Trametes versicolor — formerly known as Coriolus versicolor and Polyporus versicolor — is an extremely common polypore mushroom which can be found throughout the world. Versicolor means ‘of several colours’ and it is true that this mushroom is found in a wide variety of different colours. T. versicolor is commonly called Turkey Tail in the United States because of its resemblance to the tail of the wild turkey. T. versicolor is recognized as a medicinal mushroom in Chinese medicine under the name yun zhi (simplified Chinese: ??, traditional Chinese: ? ?). In China and Japan T. versicolor is used as in immunoadjuvant therapy for cancer.[…]

CIMER – Coriolus versicolor (mushroom) – MD Anderson Cancer Center Page 1

The anti-cancer and immune stimulating properties of Coriolus versicolor have been attributed to two extracts from its cultured mycelium (thread-like extensions). These extracts are both protein-bound polysaccharides known as polysaccharide K (PSK) and polysaccharide-peptide (PSP). Hot water is required to extract these active components. {…}

Coriolus versicolor Detailed Scientific Review

Mushrooms have been used for at least 5000 years for nutritional and medicinal purposes1,2. Anti-viral and anti-cancer effects have been demonstrated in more than 50 species through animal and in vitro studies. Six components of these mushrooms have been investigated for their activity in human cancers: the lentinan component of shiitake, schizophyllan, active hexose correlated compound (AHCC), maitake D-fraction and two components of Coriolus versicolor. According to the review by Kidd, lentinan and schizophyllan have limited oral bioavailability, and the AHCC and maitake D-fractions are still in the early stages of investigation, but the two Coriolus versicolor components have been extensively investigated and show promise2.[…]

What is Coriolus Versicolor?

Dr. Kidd believes that this ongoing stimulation by the wide array of glycans in Coriolus Versicolor keeps the immune system in a “yellow-alert” mode, ready to respond to any threat rapidly and with a more intense and complete response. Yet Coriolus Versicolor does not stimulate false or autoimmune responses.[…]

Yun Zhi Polysaccharopeptide (PSP) and the general aspects of its research

Yun Zhi Polysaccharopeptide (PSP) is a new type of BRM (Biological Response Modifier) extracted from the deep layer cultivated mycelia of Cov-1 strain of Yun Zhi (Coriolus versicolor). Its active ingredient is a protein bound polysaccharide used in the BRM therapy of tumours. Its characteristics and the general aspects of its research are briefly introduced in this paper[…]
