Summary of "Immunoadjuvant Efficacy of N-Carboxymethyl Chitosan for Vaccination via Dendritic Cell Activation."

Abstract To induce humoral- and cell-mediated immune responses in protein-based vaccinations, immunoadjuvants are needed. In this study, we investigated the immunoadjuvant effect of N-carboxymethyl chitosan (N-CMCh) on the vaccination system through dendritic cell activation. The results showed that N-CMCh nanoparticle enhanced the secretion of cytokines (interleukin [IL]-6, IL-12p70, and tumor necrosis factor-α) and antigen uptake in bone marrow-derived dendritic cells. This activated antigen-specific Th1 cell responses, including IL-2 and interferon-gamma production and proliferation. In addition, N-CMCh delayed the dissemination of ovalbumin (OVA) from an injection site in female C57BL/6 mice. As a result, in the subcutaneous vaccination, OVA-N-CMCh nanoparticles enhanced both humoral and cell-mediated vaccine responses.

Medical and Biotech [MESH] Definitions

Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (Birbeck granules). They are found principally in the stratum spinosum of the EPIDERMIS and are rich in Class II MAJOR HISTOCOMPATIBILITY COMPLEX molecules. Langerhans cells were the first dendritic cell to be described and have been a model of study for other dendritic cells (DCs), especially other migrating DCs such as dermal DCs and INTERSTITIAL DENDRITIC CELLS.

Non-hematopoietic cells, with extensive dendritic processes, found in the primary and secondary follicles of lymphoid tissue (the B cell zones). They are different from conventional DENDRITIC CELLS associated with T-CELLS. They are derived from MESENCHYMAL STEM CELLS and are negative for class II MHC antigen and do not process or present antigen like the conventional dendritic cells do. Instead, follicular dendritic cells have FC RECEPTORS and C3B RECEPTORS that hold antigen in the form of ANTIGEN-ANTIBODY COMPLEXES on their surfaces for long periods for recognition by B-CELLS.

Rare malignant neoplasm of dendritic LANGERHANS CELLS exhibiting atypical cytology, frequent mitoses, and aggressive clinical behavior. They can be distinguished from other histiocytic and dendritic proliferations by immunohistochemical and ultrastructure studies. Cytologically benign proliferations of Langerhans cells are called LANGERHANS CELL HISTIOCYTOSIS.

Sarcoma of FOLLICULAR DENDRITIC CELLS most often found in the lymph nodes. This rare neoplasm occurs predominately in adults.

Peptidoglycan immunoadjuvant originally isolated from bacterial cell wall fragments; also acts as pyrogen and may cause arthritis; stimulates both humoral and cellular immunity.
