Suppressor of cytokine signaling 2 (SOCS2) contributes to encephalitis in a model of Herpes infection in mice.

The most severe manifestation of Herpes Simplex Type 1 virus (HSV-1) infection is encephalitis characterized by arousal impairment and seizures that can evolve to coma and death. Previous studies reported the involvement of suppressor of cytokine signaling (SOCS) proteins, specifically SOCS1 and SOCS3, in HSV-1 infection, suggesting that other members of this family could be involved in the immune response against HSV-1. No previous study has reported the role of SOCS2 in HSV-1 infection.

Behavioral investigation of mice with experimental autoimmune encephalomyelitis.

Multiple sclerosis is a neuroinflammatory disease that results in serious neurological disability. Besides physical impairment, behavioral symptoms are also common in patients with multiple sclerosis. Experimental autoimmune encephalomyelitis (EAE) is considered to be a model of multiple sclerosis and mimics the main features of the disease, such as demyelination and motor impairment.

Serum levels of chemokines in Parkinson's disease.

Objective: Neuroinflammatory processes seem to contribute to the degeneration of dopaminergic neurons in Parkinson's disease (PD). Chemokines play a role in the pathogenesis of inflammatory diseases, acting mainly as mediators of leukocyte recruitment to inflammatory sites. The aim of the present study was to compare the serum levels of chemokines between healthy subjects and PD patients and to correlate these levels with the severity of PD.

Absence of PAF receptor alters cellular infiltrate but not rolling and adhesion of leukocytes in experimental autoimmune encephalomyelitis.

Experimental autoimmune encephalomyelitis (EAE) is a condition induced in some susceptible species to the study of multiple sclerosis (MS). The platelet activating factor (PAF) is an important mediator of immune responses and seems to be involved in MS. However, the participation of PAF in EAE and MS remains controversial.

Anxiety-like behavior and proinflammatory cytokine levels in the brain of C57BL/6 mice infected with Plasmodium berghei (strain ANKA).

Cerebral malaria (CM) is a severe complication resulting from Plasmodium falciparum infection. The underlying mechanisms of CM pathogenesis remain incompletely understood. The imbalance between the release of proinflammatory and anti-inflammatory cytokines has been associated with central nervous system dysfunction found in human and experimental CM.

Absence of PI3Kgamma leads to increased leukocyte apoptosis and diminished severity of experimental autoimmune encephalomyelitis.

Phosphatidylinositol-3-kinase gamma (PI3Kgamma) plays an important role in the motility of leukocytes in several models of inflammation. In this work, the role of PI3Kgamma in experimental autoimmune encephalomyelitis (EAE) was investigated. EAE was induced in wild-type and PI3Kgamma deficient mice (PI3Kgamma(-)(/)(-)).

[Paracoccidioidomycosis compromising the central nervous system: a systematic review of the literature].

This study is the first systematic review of cases of neuroparacoccidioidomycosis available in the literature. Through searches in the MEDLINE and LILACS databases, 257 cases were found in 81 published studies, mainly after the 1970s-1980s. Approximately 93% of the patients were men, especially farm laborers, with a mean age of 43 years.

Successful vaccination against Leishmania chagasi infection in BALB/c mice with freeze-thawed Leishmania antigen and Corynebacterium parvum.

This study evaluated the potential of a Leishmania antigen vaccine in protecting BALB/c mice against Leishmania chagasi. Mice received two subcutaneous doses of L. amazonensis vaccine with Corynebacterium parvum and subsequent boost was done without adjuvant.
