Inosiplex, a stimulating agent for normal human T cells and human leukocytes
Journal of Immunology (Baltimore, Md. : 1950)
|September 1, 1978
Summary
Inosiplex was found to boost the function of human immune cells, including T cells and monocytes, in laboratory tests. This suggests that inosiplex possesses immunostimulant properties.
Area of Science:
- Immunology
- Pharmacology
Background:
- Leukocyte assays are crucial for evaluating immune function.
- Inosiplex is a compound with potential immunomodulatory effects.
Purpose of the Study:
- To investigate the in vitro effects of inosiplex on various human leukocyte functions.
- To determine if inosiplex exhibits immunostimulant properties.
Main Methods:
- In vitro testing of normal human leukocytes.
- Mixed lymphocyte cultures (MLC) assays.
- Rosette formation assays (T rosettes, autologous red cell T rosettes, total T rosettes, EAC rosettes).
- Leukocyte adherence inhibition (LAI) test.
- Phagocytosis assay.
Main Results:
- Inosiplex enhanced mixed lymphocyte culture responses at 200-500 microgram/ml.
- Increased active T rosettes (50-500 microgram/ml) and autologous red cell T rosettes (100 microgram/ml).
- Did not affect total T rosettes or EAC rosettes.
- Increased nonadherent leukocytes in LAI test (100-300 microgram/ml).
- Enhanced monocyte phagocytosis of yeast (50-500 microgram/ml).
Conclusions:
- Inosiplex demonstrates significant immunostimulant properties.
- The drug enhances the function of human T cells, monocytes, and potentially neutrophils in vitro.
- These findings support the potential therapeutic use of inosiplex for immune modulation.
