Mechanism of action of C. parvum on a solid, subcutaneous mouse tumour. 1977

P D Jones, and T E Sadler, and J E Castro

The effects of i.v. C. parvum on the growth of a.s.c. inoculum of the Lewis lung carcinoma were studied in normal C57 B1 mice, and in those in which separate components of the immune response were impaired. C. parvum given either at the same time as tumour inoculation or when the carcinoma was 1 cm in diameter, and fully vascularised, reduced tumour growth. Macrophages were impaired by silica (Si), cortisone acetate (CA) or trypan blue (TB), and T cells by thymectomy and sublethal irradiation (TXR) or antilymphocyte serum (ALS). TB did not affect tumour size, whereas Si, CA, TXR, or ALS (initiated before tumour inoculation) reduced it. When C. parvum was given in combination with TB, or ALS (initiated after tumour inoculation), its antitumour effects were unchanged. C. parvum given after ALS (before tumour), TXR, Si, or CA had no further effect on tumour growth. We have shown that C. parvum inhibits the growth of inoculated Lewis tumour. However, it has not been possible to clearly define in vivo the immunological mechanisms involved.

D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D011425	Propionibacterium acnes	A bacteria isolated from normal skin, intestinal contents, wounds, blood, pus, and soft tissue abscesses. It is a common contaminant of clinical specimens, presumably from the skin of patients or attendants.	Corynebacterium acnes,Corynebacterium parvum
D003348	Cortisone	A naturally occurring glucocorticoid that has been used in replacement therapy for ADRENAL INSUFFICIENCY and as an anti-inflammatory agent. Cortisone itself is inactive; it is converted in the liver to the active metabolite HYDROCORTISONE.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D000961	Antilymphocyte Serum	Serum containing GAMMA-GLOBULINS which are antibodies for lymphocyte ANTIGENS. It is used both as a test for HISTOCOMPATIBILITY and therapeutically in TRANSPLANTATION.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
