The Role of IgE in Crohn's Disease by Impairing the Capacity of Plasmacytoid Dendritic Cells to Generate FOXP3 Tregs.

Background: A causal relationship between Crohn's disease (CD) and asthma is reported, but the underlying mechanisms are not fully understood. We sought to investigate the role of IgE and IgE-mediated pathways in the pathophysiology of CD.

Methods: 20 CD patients, 10 allergic patients without inflammatory bowel disease, and 10 healthy donors (HD) were included in the study.

Cannabinoid WIN55,212-2 reprograms monocytes and macrophages to inhibit LPS-induced inflammation.

Introduction: Chronic or uncontrolled activation of myeloid cells including monocytes, macrophages and dendritic cells (DCs) is a hallmark of immune-mediated inflammatory disorders. There is an urgent need for the development of novel drugs with the capacity to impair innate immune cell overactivation under inflammatory conditions. Compelling evidence pointed out cannabinoids as potential therapeutic tools with anti-inflammatory and immunomodulatory capacity.

C-Type Lectin Receptor Mediated Modulation of T2 Immune Responses to Allergens.

Purpose Of Review: Allergic diseases represent a major health problem of increasing prevalence worldwide. In allergy, dendritic cells (DCs) contribute to both the pathophysiology and the induction of healthy immune responses to the allergens. Different studies have reported that some common allergens contain glycans in their structure.

Ligelizumab impairs IgE-binding to plasmacytoid dendritic cells more potently than omalizumab and restores IFN-α production and FOXP3 Treg generation.

Background: Ligelizumab is an anti-IgE monoclonal antibody binding IgE with higher affinity than omalizumab that is under clinical investigation for several IgE-mediated diseases. We previously showed that omalizumab removes IgE bound to FcεRI on plasmacytoid dendritic cells (pDCs) and restores their ability to produce IFN-α and regulatory T cells (Tregs). The aim of this work is to investigate the capacity of ligelizumab to regulate functional properties of pDCs in comparison with omalizumab.

Prevalence of Sexual Dysfunction in Mexican Women with Rheumatoid Arthritis.

We estimate the prevalence and identified the associated factors of sexual dysfunction in Mexican women with rheumatoid arthritis (RA). A cross-sectional survey was applied to 100 women with RA and compared with 100 healthy, sexually active, adult women. Assessments included an interview using the Female Sexual Function Index (FSFI).
