A 22-year-old was recently diagnosed with acquired immunodeficiency syndrome (AIDS). CD4+ T-helper lab finding would be expected to accompany this virus.
The best chance for vaccination protection is provided by CD4+ T cells, which are essential for preventing Mycobacterium tuberculosis (Mtb) infection. However, little is known about the characteristics of Mtb-specific CD4 T cells that mediate control, and the absence of correlates of protection makes it extremely difficult to develop new, rational vaccines and therapeutic alternatives—both of which are urgently needed. In this article, we discuss the properties of protective CD4 T cells, including recent evidence for IFN-dependent and independent mechanisms of protection, the inadequate protection of terminally differentiated cells, and the importance of T cell migratory capacity for the treatment of Mtb infection. The leading infectious disease-related cause of illness and death among individuals around the world is tuberculosis (TB). According to estimates, Mycobacterium TB (Mtb), which is thought to impact one-third of the world's population, causes 8.7 million new cases of the disease and 1.4 million fatalities per year. Drug-resistant TB strains are becoming more prevalent; in some regions, their frequency peaked in 2011 at 19%.
