Abstract
Toxoplasma gondii infection induces a strong immunity in the host. Although the response is manifested by innate response during early infection, adaptive immunity is critical for long-term protection. Amongst the adaptive immune response CD4 T cells play an important helper role for CD8 T cells which are the primary effector cells responsible for controlling the infection. Notwithstanding the induction of robust CD8 T immunity during acute infection, the parasite is not eradicated. One of the reasons for this is the functional exhaustion of CD8 T cells during latent infection. Recent studies from our laboratory have reported that primary cause of CD8 T cell exhaustion is compromised CD4 T cell help during latent toxoplasmosis. CD8 T cell dysfunctionality is preceded by CD4 exhaustion and effector immunity is severely compromised.
期刊介绍:
Current Clinical Microbiology Reports commissions expert reviews from leading scientists at the forefront of research in microbiology. The journal covers this broad field by dividing it into four key main areas of study: virology, bacteriology, parasitology, and mycology. Within each of the four sections, experts from around the world address important aspects of clinical microbiology such as immunology, diagnostics, therapeutics, antibiotics and antibiotic resistance, and vaccines. Some of the world’s foremost authorities in the field of microbiology serve as section editors and editorial board members. Section editors select topics for which leading researchers are invited to contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, which are highlighted in annotated reference lists. These timely reviews of the literature examine the latest scientific discoveries and controversies as they emerge and are indispensable to both researchers and clinicians. The editorial board, composed of more than 20 internationally diverse members, reviews the annual table of contents, ensures that topics address all aspects of emerging research, and where applicable suggests topics of critical importance to various countries/regions.
