Multiplex Cytokine Profiling of Stimulated Mouse Splenocytes Using a Cytometric Bead-based Immunoassay Platform
Published on: November 9, 2017
Insights
Immune cells in leprosy lesions produce specific cytokine profiles that determine whether the body resists or succumbs to M. leprae infection. These profiles are key to understanding leprosy progression.
Area of Science:
- Immunology
- Molecular Biology
- Infectious Disease Research
Context:
- Cytokines are crucial immune system effectors, acting in soluble or membrane-associated forms.
- Studying immune cell communication in leprosy involves analyzing blood serum or infected tissues.
- Local cytokine production dictates the immune response to M. leprae.
Purpose:
- To investigate the role of local cytokine secretion profiles in M. leprae infection outcomes.
- To compare various methods for cytokine and lymphokine detection in leprosy research.
Summary:
- Cytokine and lymphokine detection can be achieved through bioassays, antibody-based systems (e.g., ELISA, Elispot), or molecular biology techniques (e.g., PCR, mRNA analysis).
- Research in leprosy patients reveals distinct cytokine secretion profiles in infected tissues.
- These local profiles correlate directly with the host's resistance or susceptibility to M. leprae.
Impact:
- Understanding local cytokine dynamics provides critical insights into leprosy pathogenesis.
- Identifying specific cytokine profiles can inform the development of targeted immunotherapies for leprosy.
- This research highlights the importance of tissue-specific immune responses in infectious diseases.
Abstract:
One of the functions expressed by the effectors of the immune system is the synthesis of cytokines, either in soluble form or associated with the membrane. Study of this communication network between the different compartments of the immune system can be conducted either in the blood (serum) of leprosy patients or directly in the infected tissues. The key to how the immune response will develop lies in the nature of the cytokines produced locally by the immune cells. For the characterization and detection of cytokines/lymphokines we may use either biological methods (bioassay), or antibody-based detection systems (RIA, Elisa, Elispot, immunocytochemistry using monoclonal antibodies), or techniques derived from molecular biology (Polymerase chain reaction-PCR, analysis of messenger RNA, and hybridization in situ). These various techniques, whose advantages and disadvantages are discussed, have demonstrated that locally, in the infected lesions, resistance and/or susceptibility to M. leprae infection correlates with differing cytokine secretion profiles.
