Genetic Hearing Loss Associated With Autoinflammation.

Sensorineural hearing loss can result from dysfunction of the inner ear, auditory nerve, or auditory pathways in the central nervous system. Sensorineural hearing loss can be associated with age, exposure to ototoxic drugs or noise, or mutations in nuclear or mitochondrial genes. However, it is idiopathic in some patients.

Interleukin-12-producing CD103+ CD11b- CD8+ dendritic cells are responsible for eliciting gut intraepithelial lymphocyte response against Encephalitozoon cuniculi.

Microsporidia, which belong to the kingdom Fungi, are important opportunistic pathogens in HIV-infected populations and organ transplant recipients that are often associated with a broad range of symptoms, such as diarrhea, nephritis, and encephalitis. Natural infection occurs via the oral route, and as a consequence, gut immunity plays an important role in restricting the dissemination of these pathogens. Studies from our laboratory have reported that the pathogens induce a rapid intraepithelial lymphocyte (IEL) response important for host protection.

Effector CD8 T cell immunity in microsporidial infection: a lone defense mechanism.

Microsporidia is a group of pathogens, which can pose severe risks to the immunocompromised population such as HIV-infected individuals. The expertise to diagnose these pathogens is limited and therefore their prevalence is believed to be much higher than what is currently known. In a mouse model of infections, it has been reported that CD8 T cells are the primary effector cells responsible for protecting the infected host.
