Flow Cytometry - Alexa Fluor® 647 Anti-CD86 antibody [OX48] (AB256271)
Lewis rat splenocytes treated with 10 μg/ml LPS for 3 days were stained with ab256271 (right) or mouse IgG1κ Alexa Fluor® 647 isotype (left). 10 μg/ml LPS for 3 days were incubated for 30 min on ice in 1x PBS containing 10 % rat serum to block FC receptors and non-specific protein-protein interaction followed by the antibody (ab256271) or mouse IgG1κ Alexa Fluor® 647 isotype (1x 106 in 100 μl at 1 μg/ml (1/500)) for 30 min on ice. The cells were simultaneously stained with CD45R.
Acquisition of >30,000 events were collected using a 40 mW Red laser (640nm) and 670/14 bandpass filter. Events were gated on live lymphocytes.

Biological function summary
CD86 plays a significant role in the immune system by providing secondary signals for T cell activation and differentiation. It is a part of the B7 protein family and forms a complex with CD28 and CTLA-4 on T cells. When CD86 binds to CD28 it sends positive co-stimulatory signals which promote T cell proliferation and cytokine production. On the other hand interaction with CTLA-4 transmits an inhibitory signal which reduces immune response. This dual interaction helps to balance immune activation and tolerance.
Pathways
CD86 takes part in important immune-related signaling pathways particularly the T cell receptor signaling pathway and the PI3K-Akt signaling pathway. Both pathways are fundamental for initiating immune responses. CD86's interaction with CD28 activates downstream signaling cascades including PI3K-Akt which is important for cell survival and growth. Additionally CD86 collaborates with other proteins such as CD80 another co-stimulatory molecule to amplify T cell activation within these pathways.
