Immunogen

Specificity

Although this clone performed well in IHC-P on tonsil tissue, non-specific nuclear staining was seen on TMA. The staining pattern did not correlate with ISH, so we cannot recommend this clone for IHC.

Supplementary information

PD-L2 also known as PDCD1LG2 or B7-DC is a member of the B7 protein family that plays a role in immune system regulation. This protein has a molecular mass of approximately 25 kDa. PD-L2 is expressed in antigen-presenting cells such as dendritic cells and macrophages. Expression is also located in some subsets of T cells and B cells. The PD-L2 can act as a second ligand for the PD-1 receptor which is important in immune checkpoints.
Biological function summary

PD-L2 offers protection to tissues from autoimmunity by regulating T-cell activation and fostering tolerance. By engaging with its receptor PD-1 PD-L2 forms a complex that modulates the immune response to prevent overactivation. This interaction limits the immune system's potential damage to healthy tissues maintaining proper immune function in diverse environments.

Pathways

PD-L2 participates in the immune checkpoint pathways where it works closely with PD-1 to mediate immune responses. PD-L2 forms an important part of the program death-1 (PD-1) pathway which plays a prominent role in downregulating T-cell activity. It relates to proteins such as PD-L1 which also interacts with PD-1 modulating immune tolerance and response to infections or tumors.

PD-L2 involvement has been significant in cancer immunology and autoimmune conditions. Its interaction with PD-1 relates to the suppression of immune responses in tumors contributing to cancer progression. PD-L2's function as an immune checkpoint ligand associates with autoimmune diseases like rheumatoid arthritis where immune regulation goes awry. Both PD-1 and PD-L2 represent potential targets for therapeutic interventions due to their roles in these conditions.
