DH82 Cells

DH-82 cells, derived from the malignant histiocytosis of a ten-year-old male Golden Retriever, are a cornerstone in the study of canine immunology and related diseases.
These cells exhibit a macrophage-like morphology, mirroring the key functions of human macrophages, thereby providing a relevant model for investigating various aspects of canine health, particularly immune system-related conditions.
A defining characteristic of DH-82 cells is their capability to phagocytize latex particles, an essential function of macrophages responsible for the elimination of foreign substances in the body. This property positions DH-82 cells as a robust tool for delving into the immune responses of dogs, especially in the face of infections and inflammatory diseases. The expression of Fc gamma receptors in DH-82 cells is a notable trait.
These receptors are integral to immune responses, as they bind to antibodies and facilitate the phagocytosis of antibody-coated pathogens or particles. This makes DH-82 cells particularly valuable in studies focusing on immune responses and antibody-dependent cellular cytotoxicity (ADCC). In contrast, DH-82 cells do not express Fc mu and C3b receptors.
The absence of Fc mu receptors, typically found on B cells and involved in antigen presentation, and C3b receptors, which bind to complement proteins in immune responses, provides a controlled setting for examining specific immune mechanisms that might be influenced by these receptors.
Additionally, DH-82 cells are non-producers of IL-1, a pivotal cytokine in inflammatory responses. This feature offers a unique perspective for investigating the role of IL-1 in various biological processes and understanding IL-1-mediated diseases.
In the realm of infectious diseases, DH-82 cells have proven particularly useful in studying canine monocytic ehrlichiosis (CME), a tick-borne illness caused by Ehrlichia canis.
The cells provide a conducive environment for the bacterium' s growth, aiding in the exploration of the disease' s development and potential treatments. The doubling time of DH-82 cells, approximately 26 hours, is also a critical aspect in their use, influencing experimental design and the interpretation of results.

Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.
To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.
