Signals That Cause an Immune Cell to Change Shape Can Compete to Influence the Immune Response.

Abstract

Infectious diseases caused by viruses and bacteria remain a significant health problem. CD46 is a protein on the surface of human cells that is used by a number of viruses and bacteria to enter and infect host cells. Through binding to the CD46 protein, viruses and bacteria can induce changes in immune cells, such as T lymphocytes, that affect the way our immune system responds to infection. For example, immunosuppression induced by infection with measles virus is the primary cause of the mortality and morbidity associated with the disease, and is a phenomenon that is poorly understood. However, there is evidence to suggest that the interaction between measles-infected cells with CD46 on the..
