Lymphatic filariasis is a debilitating vector borne parasitic disease that infects human lymphatic system by nematode Brugia malayi. Currently available anti-filarial drugs are effective only on the larval stages of parasite. So far, no effective drugs are available for humans to treat filarial infections. In this regard, aspartate semialdehyde dehydrogenase (ASDase) in lysine biosynthetic pathway from Wolbachia endosymbiont Brugia malayi represents an attractive therapeutic target for the development of novel anti-filarial agents...

INTRODUCTION: HIV affects more women than any other life-threatening infectious agent, and most infections are sexually transmitted. HIV must breach the female genital tract mucosal barrier to establish systemic infection, and clinical studies indicate virus more easily evades this barrier in women using depot-medroxyprogesterone acetate (DMPA) and other injectable progestins for contraception. Identifying a potential mechanism for this association, we learned DMPA promotes susceptibility of wild-type mice to genital herpes simplex virus type 2 (HSV-2) infection by reducing genital tissue expression of the cell-cell adhesion molecule desmoglein-1 (DSG-1) and increasing genital mucosal permeability...

INTRODUCTION: The vaccination against Humanpapilloma Virus (HPV) is an effective strategy to prevent high-risk HPV infection and subsequent cervical carcinogenesis. Although the safety profile has been ascertained, the relation with the development of central nervous system (CNS) autoimmune disorders (AD) appears still controversial. Multiple Sclerosis (MS) is the most common cause of chronic neurological impairment in young people, typically striking females. The main purpose of this review was to assess the association between HPV vaccination and MS...

Autophagy is an intracellular conservative degradation pathway. This event has been considered as a key step in host defense against bacterial infection. However, Porphyromonas gingivalis, as one of the evidence-sufficient periodontal pathogens, can utilize self-induced autophagy to achieve persistent intracellular survival and proliferation, which enable this organism to escape from host immune surveillance. This review focuses on molecular mechanism of P. gingivalis internalization and autophagy to illuminate its pathogenesis and to further explore the relationship between P...

Systemic inflammation mediated by Plasmodium parasites is central to malaria disease and its complications. Plasmodium parasites reside in erythrocytes and can theoretically reach all host tissues via the circulation. However, actual interactions between parasitized erythrocytes and host tissues, along with the consequent damage and pathological changes, are limited locally to specific tissue sites. Such tissue specificity of the parasite can alter the outcome of malaria disease, determining whether acute or chronic complications occur...

Sweet's syndrome is a skin manifestation of various systemic infections, drugs, malignancies and autoimmune disorders. There are very few case reports describing the relationship between Sweet's syndrome and non-tubercular mycobacterium infection. Further development of Sweet's syndrome secondary to mycobacterium tuberculosis (active pulmonary tuberculosis) is extremely uncommon and this is the second well established case reported from India. Here we report a forty eight year old man who presented with multiple erythematous and tender plaques over neck, palms and sides of soles...

Plants have evolved a sophisticated innate immune system to contend with potential infection by various pathogens. Understanding and manipulation of key molecular mechanisms that plants use to defend against various pathogens are critical for developing novel strategies in plant disease control. In plants, resistance to attempted pathogen infection is often associated with hypersensitive response (HR), a form of rapid programmed cell death (PCD) at the site of attempted pathogen invasion. In this chapter, we describe a method for rapid identification of genes that are essential for plant innate immunity...

Mitsuhiro Yamada, Masakazu Ichinose
Over the past few decades, it has been clarified that the nervous system and immune system have overlapping distributions and their interactions are critical in the regulation of immunological and inflammatory responses. The cholinergic anti-inflammatory pathway, including the parasympathetic nerve systems and humoral factors orchestrate the immune responses to protect the body during infection and tissue injury. Recent investigations have attempted to clarify how the parasympathetic nerve systems attenuate the systemic inflammatory responses and identified the α7 nicotinic acetylcholine receptor (α7nAChR) as a crucial target for attenuating the release of inflammatory cytokines from inflammatory cells including macrophages and dendritic cells...
