Human Papillomavirus and Cancer - Immunological Consequences of MHC Class I Down-Regulation

Few studies have been conducted on the causative factors associated with the development of cancer. Infection by high risk human papillomaviruses (HPVs) have been implicated as causative agents in a variety of cancers. HPV is capable of evading immune system and establishing persistent infections. Prolonged infection and lesion maintenance are associated with higher risk of neoplastic progressi...

Regulation of MHC Class I by Viruses

Originally recognized for their role in triggering T cell responses that caused the rejection of transplanted tissue, it is now known that MHC-encoded molecules are involved in immunesurveillance and antigen presentation to T lymphocytes. These MHC molecules act as “signposts” that displays fragmented pieces of an antigen (viral proteins in virus-infected cells or mutated proteins in tumor cell...

Stable Down-Regulation of HLA Class-I by Serum Starvation in Human PBMCs

Background: The human leukocyte antigen (HLA) matching between organ donor and recipient is an acceptable strategy in clinical transplantation since 1964. However, in bone marrow transplantation, finding matched donors is often problematic. Thus new method for down regulation of HLA can be an alternative strategy to solve this problem. Objective: To examine the effect of serum starvation on HLA...
