Immunogenicity Services from ProImmune understand the mechanisms that can lead to immunogenicity risk through focussed experimental investigation Unwanted immunogenicity to biotherapeutics is a complex and multifactorial challenge. When developing any protein product, it is a potential problem that must be addressed. Unwanted immune responses that target your drug can lead to neutralization. HLA antigens are either high expression such as HLA‐A, B, C (class I), DRB1 (class II), or low expression such as DQB1, DPB1, and DRB3/4/5 (all class II). The high expression antigens play a pivotal role in the transplant setting because of high antigen density on the cells HLA stands for human leukocyte antigen. Antigens are special proteins found on the surface of white blood cells (also called leukocytes). You inherit your HLA typing from your parents. HLA typing is used to determine how well a donor matches a patient. Blood samples or cheek swab samples are used to determine HLA typing The first statement is numbered 1 and the second is numbered 2. For example: 1. A positive family history of ankylosing spondylitis (AS) is often found in patients with this disease. 2.
