Case Study: Mechanism for Increased Follicular Helper T Cell Development in Activated PI3K Delta Syndrome
This study was carried out after written informed consent from all subjects. All subjects gave written informed consent in accordance with the Declaration of Helsinki. The protocol was approved by the Stanford University and UCLA Institutional Review Boards. Author Contributions MB provided patient care and obtained IRB approval. RO prepared histology images. MB, TT, and RB designed the research. TT and LP conducted experiments and analyzed data. MB made the molecular model. MB and TT wrote the manuscript. Funding Funding for this work came from the Jeffrey Modell Foundation and from the NIH/NIGMS (R01 GM110482 to MB)....

Mind the Gap: How Interspecies Variability in IgG and Its Receptors May Complicate Comparisons of Human and Non-human Primate Effector Function
Conclusions The sheer number of factors to consider when translating observations between macaques and humans makes the process a challenging, multidimensional one. Differences in the structures and activities of IgG subclasses, and polymorphisms in protein sequence and post-translational modification of antibody receptors are a subset of the many relevant considerations. Copy number variation, splice variants, and alleles with sequence variation outside of coding regions have been associated with a diversity of phenotypes in humans (183, 213–217), and are presumed to exist in NHP. A number of differences in the p...

The Risk of Progressive Multifocal Leukoencephalopathy Under Biological Agents Used in the Treatment of Chronic Inflammatory Diseases.
Abstract Biological agents such as monoclonal antibodies and soluble cytokine receptors have taken on an expanding role in the treatment of chronic immune mediated diseases. Progressive multifocal leukoencephalopathy (PML) is a rare central neurological disease caused by JC virus infection that has been described in the setting of conditions with severe impairment of immune surveillance, such as haematological malignancies, stem cell or solid organ transplantation and AIDS. This serious demyelinating disease has recently been described in patients receiving monoclonal antibodies for chronic inflammatory diseases s...

Rituximab for tumefactive demyelination refractory to corticosteroids and plasma exchange
Case history A 38-year-old woman with no significant past medical history presented with a generalised tonic–clonic seizure. The patient was afebrile and general physical and neurological examinations were normal. MRI of the brain revealed an irregular mass in the right temporal lobe with T2-weighted and fluid-attenuated inversion recovery (FLAIR) signal hyperintensity and heterogeneous enhancement after the administration of gadolinium (figure 1A–D). Laboratory investigations included normal blood count, liver enzymes, serum creatinine, angiotensin converting enzyme and erythrocyte sedimentation rate (ESR). Se...

Fever and confusion in a returning soldier
A 36–year–old army engineer returned from a 6–week deployment in Afghanistan. He had complained of upper respiratory tract infection even before his travel. On return he was found to be increasingly sleepy and later developed unsteadiness, slurred speech and confusion. His initial blood tests were normal, with CSF and MRI suggesting signs of encephalitis. He continued to deteriorate, requiring intubation and ventilation. Several bacterial, viral, protozoal and fungal tests were negative. He developed pancytopenia requiring frequent packed red cell and platelet transfusions. Spleen was found to be marginal...
