Background CD4^+T cell counts have been used as the indicator of human immunodeficiency virus type 1 (HIV-1) disease progression and thereby to determine when to start highly active antiretroviral therapy (HAART)...
Interleukin-15 (IL-15) is essential for the survival of memory CD8^+ and CD4^+ T cell subsets, and natural killer and natural killer T cells. Here, we describe a hitherto unreported role of IL-15 in regulating hom...
Transcription factors and DNA/histone modification enzymes work in concert to establish and maintain cell identity. CD4^+ and CD8^+ T cells are key players in cellular immunity with distinct functions. Recent studie...
The occurrence of massive CD4+ T cell depletion is one of the most prominent characteristics of human immunodeficiency virus type 1 (HIV-1) infection during acute phase, resulting in unrestorable destruction to the im...

Background The mechanism of chronic immune activation and impairment of HIV-specific immune responses during chronic infection is not fully understood. However, it is known that high immune activation leads to more ra...
This study was supported in part by the National Natural Science Foundation of China (No. 30460051), and in part by the Program NCET-04-0835 for New Century Excellent Talents in Chinese Universities.
Bronchial asthma is a chronic inflammatory disease of the airways that is characterized by lymphocyte, eosinophil, and mast cell infiltration of the submucosa along with mucous gland hyperplasia and subepithelial fibr...

To better understand the interaction between Schistosoma japonicum and its murine host, we characterized the immune response of CD4^+ T cells generated during an experimental S. japonicum infection based on different...
