PPD-induced monocyte chemotactic factor production by human milk cells
Acta Paediatrica Scandinavica
|July 1, 1984
Summary
Breast milk cells can produce immune mediators like monocyte chemotactic factor when stimulated by antigens. This study shows functional capability of colostral cells in postpartum women to generate these important immunologic signals.
Area of Science:
- Immunology
- Cell Biology
- Lactation Biology
Background:
- Breast milk contains immune cells crucial for infant protection.
- Antigen exposure can prime immune responses in postpartum mothers.
- The production of specific immunologic mediators by colostral cells is not fully understood.
Purpose of the Study:
- To investigate the functional capacity of antigen-stimulated breast milk cells.
- To determine if colostral cells can produce monocyte chemotactic factor (MCF).
- To compare the immune mediator production of colostral cells with peripheral blood cells.
Main Methods:
- Colostrum and peripheral blood samples were collected from ten women 2-4 days postpartum.
- Mononuclear cells from these samples were cultured and stimulated with purified protein derivative (PPD).
- Supernatants were assayed for the presence of monocyte chemotactic factor (MCF).
Main Results:
- Four out of six women with a history of positive tuberculin skin test or BCG immunization showed MCF production.
- Both peripheral blood lymphocyte cultures and colostrum cell cultures from these women produced MCF.
- This indicates antigen-specific immune mediator production by colostral cells.
Conclusions:
- Antigen-stimulated colostral cells possess the functional capability to produce immunologic mediators.
- Breast milk cells contribute to the maternal immune response and potentially infant immunity.
- Further research into the role of these mediators in early life immunity is warranted.
