Sialic Acid Binding Ig Like Lectin 14 (SIGLEC14) Antibody

Background

SIGLEC14 is a member of the Siglec family expressed on myeloid cells, including monocytes and neutrophils. It is paired with SIGLEC5, with which it shares high sequence similarity, forming an activating counterpart to the inhibitory SIGLEC5. SIGLEC14 binds to sialic acid-containing glycans on pathogens and self-tissues, triggering pro-inflammatory responses. This protein has been implicated in innate immune activation, particularly in recognizing bacterial infections. SIGLEC14 also plays a role in the modulation of immune responses, balancing activation and tolerance. Genetic variations in SIGLEC14 can result in a fusion with SIGLEC5, altering its expression and immune function.
