Book Description
Our understanding of genetic predisposition to inflammatory and autoimmune diseases has been enhanced by large scale quantitative trait loci (QTL) linkage mapping and genome-wide association studies (GWAS). However, the resolution and interpretation of QTL linkage mapping or GWAS findings are limited. In this work, we complement genetic predictions for several human diseases including multiple sclerosis (MS) and systemic capillary leakage syndrome (SCLS) with genetic and functional data in model organisms to associate genes with phenotypes and diseases. Focusing on MS, an autoimmune inflammatory disease of the central nervous system (CNS), we experimentally tested the effect of three of the GWAS candidate genes (SLAMF1, SLAMF2 and SLAMF7) in the experimental autoimmune encephalomyelitis (EAE) mouse model and found a male-specific locus distal to these loci regulating CNS autoimmune disease. Functional data in mouse suggests this male-specific locus modulates the frequency of immune cells including CD11b+, TCR[alpha beta]+CD4+Foxp3+, and TCR[alpha beta]+CD8+IL-17+ cells during EAE disease. Orchiectomy experiments demonstrate that this male specific phenotype is dependent on testis but not testosterone (T) or 5[alpha]-dihydrotestosterone (DHT). Using a bioinformatic approach, we identified SLAMF8 and SLAMF9 along with other differentially expressed genes in linkage with MS-GWAS predictions whose expression is testis-dependent, but not directly regulated by T or DHT, as potential positional candidates regulating CNS autoimmune disease. Further refinement of this locus is required to identify the causal gene(s) that may be targeted for prevention and/or treatment of MS in men. Using SCLS, an extremely rare disorder of unknown etiology characterized by recurrent episodes of vascular leakage, we identified and modeled this disease in an inbred mouse strain, SJL, using susceptibility to histamine- and infection-triggered vascular leak as the major phenotypic readout. This trait "Histamine hypersensitivity" (Histh/Histh) was mapped to a region on Chr 6. Remarkably, Histh is syntenic to the genomic locus most strongly associated with SCLS in humans (3p25.3). Subsequent studies found that the Histh locus is not unique to SJL but additional mouse strains also exhibit Histh phenotype. Considering GWAS studies in SCLS are limited by the small number of patients, we utilized interval-specific SNP-based association testing among Histh phenotyped mouse strains to predict Histh candidates. Furthermore, to dissect the complexity of Histh QTL, we developed network-based functional prediction methods to rank genes in this locus by predicting functional association with multiple Histh-related processes. The top-ranked genes include Cxcl12, Ret, Cacna1c, and Cntn3, all of which have strong functional associations and are proximal to SNPs segregating with Histh. Lastly, we utilized the power of integrating genetic and functional approaches to understand susceptibility to Bordetella pertussis and pertussis toxin (PTX) induced histamine sensitization (Bphs/Bphs), a sub-phenotype with an established role in autoimmunity. Congenic mapping in mice had earlier linked Bphs to histamine H1 receptor gene (Hrh1/H1R) and demonstrated that H1R differs at three amino acid residues in Bphs-susceptible and -resistant mice. Our subsequent studies identified eight inbred mouse strains that were susceptible to Bphs despite carrying a resistant H1R allele. Genetic analyses mapped the locus complementing Bphs to mouse Chr 6, in linkage disequilibrium with Hrh1; we have designated this Bphs-enhancer (Bphse). Similar to the approaches used for Histh, we utilized interval-specific SNP based association testing and network-based functional enrichment to predict nine candidate loci for Bphse including Atp2b2, Atg7, Pparg, Syn2, Ift122, Raf1, Mkrn2, Timp4 and Gt(ROSA)26Sor. Overall, these studies demonstrate the power of integrating genetic and functional methods in humans and animal models to predict highly plausible loci underlying QTL/GWAS data.

Book Description
This volume details our current understanding of the architecture and signaling capabilities of the B cell antigen receptor (BCR) in health and disease. The first chapters review new insights into the assembly of BCR components and their organization on the cell surface. Subsequent contributions focus on the molecular interactions that connect the BCR with major intracellular signaling pathways such as Ca2+ mobilization, membrane phospholipid metabolism, nuclear translocation of NF-kB or the activation of Bruton’s Tyrosine Kinase and MAP kinases. These elements orchestrate cytoplasmic and nuclear responses as well as cytoskeleton dynamics for antigen internalization. Furthermore, a key mechanism of how B cells remember their cognate antigen is discussed in detail. Altogether, the discoveries presented provide a better understanding of B cell biology and help to explain some B cell-mediated pathogenicities, like autoimmune phenomena or the formation of B cell tumors, while also paving the way for eventually combating these diseases.

Book Description
This book examines the utility of genome-wide association studies (GWAS) in the era of next-generation sequencing and big data, identifies limitations and potential means of overcoming them, and looks to the future of GWAS and what may lay beyond. GWAS are among the most powerful tools for elucidating the genetic aspects of human and disease diversity. In Genome-Wide Association Studies, experts in the field explore in depth the impacts of GWAS on genomic research into a variety of common diseases, including cardiovascular, autoimmune, diabetic, cancer, and infectious diseases. The book will equip readers with a sound understanding both of the types of disease and phenotypes that are suited for GWAS and of the ways in which a road map resulting from GWAS can lead to the realization of personalized/precision medicine: functional analysis, drug seeds, pathway analysis, disease mechanism, risk prediction, and diagnosis.

Book Description
There are millions of people who experience issues related to brain health—depression, attention issues, anxiety, forgetfulness, fatigue, and even chronic pain—yet can’t figure out what’s causing their problems and can’t find any relief. They may have seen a myriad of doctors, many of whom do not take their complaints seriously, or worse, turn to the easy, often inappropriate fix of antidepressants or anti-anxiety medications. Traditional medications, supplements, or other therapies haven’t worked. No matter what their age—from children to teens or seniors—people and their loved ones are frustrated, scared, and confused by their continued poor health. Countless others display severe psychiatric symptoms that seem to come out of nowhere, ranging from tics, obsessive-compulsive behaviors and anxiety, to depression, bipolar-like mood swings, and even borderline personality disorder and suicidal ideas. Sometimes, the people affected are the only ones that notices a change to the way they think or feel, and they suffer in silence. Or, they reach out to try to get help, and are all too frequently misdiagnosed. David Younger, a world-renowned physician, provides relief to these patients and their families. His diagnostic techniques and treatment protocols will help readers identify the true cause of their symptoms and put them on a clear path to healing so they no longer feel unbalanced, out of control, forgetful, and exhausted. The Autoimmune Brain connects common brain health symptoms to the changes in the immune system, and particularly bacterial, viral, and parasitic infections. Younger explains his groundbreaking research and adds a new component: how traumatic stress (whether physical or emotional) and genetics affects this same triad as inextricable factors in initiating disease and brain health symptoms. In fact, a change in personality, behavior, coping style, and one’s emotional state may be the first clue that there is a health problem brewing somewhere else in the body. Readers will find new answers to troubling conditions, including: Alzheimer’s disease; Anxiety; Arthritis; Autism; Autonomic disturbances; Bacterial and viral infections; Bipolar Disorder; Cancer; Celiac disease and gluten intolerances; Chronic Fatigue Syndrome (now referred to as Systemic Exertion Intolerance Disease); Chronic Pain; Dementia; Depression; Endocrine Disorders; Immune modulatory therapy using IVIg; Lyme disease and co-infections; Mast cell activation syndrome; Medical cannabis; Obsessive Compulsive Disorder; Orthostatic hypotension; Peripheral Neuropathy; Porphyria; Post-Traumatic Stress Disorder; and Postural orthostatic tachycardia.
