Background Information


CD370, more commonly known as CLEC9A or DNGR-1 (dendritic cell NK lectin group receptor 1), is a C-type lectin–like receptor selectively expressed on a specialized subset of dendritic cells, particularly conventional type 1 dendritic cells (cDC1). These cells are highly efficient at cross-presenting antigens to CD8+ T cells, placing CD370 at the center of immune responses against viruses, intracellular pathogens, and tumors. Rather than broadly activating immunity, CD370 functions as a sensor of cellular damage and necrosis.

Structurally, CD370 is a type II transmembrane protein belonging to the C-type lectin receptor family. It contains a short N-terminal cytoplasmic tail, a single transmembrane region, and a C-terminal extracellular C-type lectin–like domain. Unlike classical lectins, CD370 does not bind carbohydrates in a calcium-dependent manner. Its cytoplasmic tail contains a conserved hemITAM (hemi–immunoreceptor tyrosine-based activation motif), which enables signaling through spleen tyrosine kinase (Syk) upon ligand engagement.

The primary ligand for CD370 is filamentous actin (F-actin), which becomes exposed when cells undergo necrosis or mechanical damage. By recognizing exposed F-actin, CD370 allows dendritic cells to selectively detect dead or damaged cells while ignoring apoptotic cells, which maintain membrane integrity. Engagement of CD370 does not strongly activate dendritic cells on its own but instead promotes the routing of captured antigens into cross-presentation pathways, enhancing presentation on MHC class I molecules and subsequent activation of cytotoxic CD8+ T cells.

CD370 plays an important role in disease contexts where cell death and antigen cross-presentation are prominent. In viral infections and cancer, CD370-expressing dendritic cells are crucial for initiating effective CD8+ T cell responses against infected or malignant cells. In autoimmune disease, dysregulated sensing of self-derived antigens from damaged tissue could contribute to pathological T cell activation, although CD370 is generally thought to promote tolerance by limiting inflammatory signaling. In cancer, CD370-positive dendritic cells are often functionally impaired within the tumor microenvironment, reducing anti-tumor immunity.

Therapeutically, CD370 is an attractive target for vaccine and immunotherapy strategies. Antigen delivery systems that target CD370 can efficiently direct antigens to cross-presenting dendritic cells, enhancing CD8+ T cell responses without excessive inflammation. This approach is being explored in cancer vaccines and antiviral immunotherapies. Because of its restricted expression pattern and specialized function, CD370 represents a promising avenue for selectively manipulating cytotoxic immune responses while minimizing off-target immune activation.

Frequently Asked Questions


What are In Vivo Star Biofunctional Antibodies?
In Vivo Star antibodies are premium-grade monoclonal antibodies purified and formulated specifically for use in animal studies. Each lot is manufactured under stringent quality controls to ensure the low endotoxin levels, high purity, and functional activity required for reliable in vivo results.

How are these antibodies different from standard research antibodies (e.g., for Western blot or flow cytometry)?
Standard research antibodies are optimized for in vitro detection assays and may contain preservatives, carrier proteins (like BSA), or higher endotoxin levels unsuitable for injection. In Vivo Star antibodies are formulated in injectable-grade, azide-free, low-endotoxin buffers and validated for functional bioactivity in living systems rather than just antigen binding.

What endotoxin and purity specifications do these antibodies meet?
All In Vivo Star antibodies are tested and certified to meet low-endotoxin thresholds (typically <1 EU/mg, lot-dependent) using the LAL (Limulus Amebocyte Lysate) assay, and are purified to ≥95% purity by SEC-HPLC or SDS-PAGE. Exact specifications are provided on the Certificate of Analysis (CoA) for each lot.

Are these antibodies azide-free and carrier-free?
All In Vivo Star antibodies are formulated without sodium azide and without carrier proteins such as BSA or gelatin, since both can interfere with animal physiology or immune readouts during in vivo studies.

Do you provide isotype controls?
Matched isotype control antibodies (same host species, isotype, and formulation) are available upon request for most clones to support proper experimental controls.

How should In Vivo Star antibodies be stored and handled?
Store at 4°C for short-term use and avoid repeated freeze-thaw cycles, which can reduce bioactivity; aliquoting is recommended for long-term storage per the product-specific storage instructions on the Certificate of Analysis. Always confirm storage conditions and expiration on the CoA that accompanies each lot, as these can vary slightly by antibody.
