    CONCLUSIONS Shouting is the predominant form of arguments between couples, with finances, jealousy and alcohol consumption being the most common causes of family disputes. In children who witness these forms of behaviour, a feeling of fear or dread predominates. INTRODUCTION People with schizophrenia and bipolar disorder (BD) have a high risk of unwanted pregnancies and abortions, due to their condition of vulnerability or hypersexuality (common in BD). This is associated with difficulty in planning their actions and lack of sex education and counselling by medical personnel, and can lead to adverse obstetric outcomes and inability to care adequately for their children. OBJECTIVE To describe the characteristics in terms of sexual and reproductive health, and the use of contraception and counselling in psychiatric consultations, in a sample of patients with BD and schizophrenia in Medellin, Colombia. METHODS Observational cross-sectional study. We included the 160 participants from the clinical trial, “The effects of a multimodal intervention programme in patients with bipolar disorder and schizophrenia”, who were recruited from the mood and psychosis disorders group clinic at Hospital Universitario de San Vicente Fundación in Medellin. They were contacted by phone byconsidered themselves to be well informed on the subject. CONCLUSIONS Patients with mental illness have cognitive and behavioural alterations that affect their sexual and reproductive lives. Psychiatrists should therefore address this issue, to ensure education in areas such as contraception, family planning and sexually transmitted diseases and help safeguard the safety and quality of life of their patients. L.U.The innate immune system represents the first defense line of the host following viral infection. The infection triggers the recognition of pathogen-associated molecular patterns (PAMPs) from the viruses by pattern recognition receptors (PRRs) of the host cell. The interaction between viral PAMPs and PRRs evokes a sophisticated signal transduction system and eventually promotes the expression of type I interferons (IFNs) and proinflammatory cytokines. Ubiquitination plays an indispensable role in fine-tuning almost every single step of this signaling cascade given on its versatile functions. see more Ubiquitin ligases and deubiquitinases (DUBs), which cooperatively and accurately regulate the dynamic and reversible ubiquitination process, are the master regulators of antiviral signaling. In this review, we concentrate on summarizing the ubiquitin ligases and DUBs that modulate the central signaling molecules in antiviral innate immunity. Especially, we emphasize the ones that were identified by the immunologists from China. © 2020 Elsevier Inc. All rights reserved.The NLRP3 inflammasome is a cytoplasmic multiprotein complex, the assembly of which can be initiated in response to various exogenous or endogenous danger signals. Excessive activation of the NLRP3 inflammasome has been implicated in the pathogenesis of a wide variety of human inflammatory diseases, suggesting that the NLRP3 inflammasome is a potential target for the treatment of these diseases. However, clinical drugs targeting the NLRP3 inflammasome are still not available. Recent data have elucidated the different signaling pathways or events that can control NLRP3 inflammasome activation and have provided some potential compounds with anti-NLRP3 inflammasome activity. Here, we summarize the molecular mechanisms and diseases involved in NLRP3 inflammasome activation and discuss the potential strategies targeting different aspects of the NLRP3 inflammasome and its implications for the treatment of inflammatory diseases. © 2020 Elsevier Inc.

Along with the growing understanding of basic NK cell biology, it has been widely accepted that NK cells are a heterogeneous population of innate lymphoid cell (ILC) family. Apart from the conventional NK cell (cNK) subset that circulates throughout the body, some non-lymphoid tissues contain tissue-resident NK (trNK) cell subsets, and the composition of NK cell subsets varies greatly with different locations. Except for cNK cells, other ILCs are known as tissue-resident cells. In this review, we summarize the unique properties of trNK cells, discuss their lineage relationship with other ILCs, and highlight recent advances in our understanding of the functions of trNK cells and other ILCs. © 2020 Elsevier Inc.

Especially, the transition metals iron (Fe), zinc (Zn), manganese (Mn), nickel (Ni), copper (Cu) and cobalt (Co) are crucial micronutrients known to play vital roles in metabolism as well due to their unique redox properties. Metals carry out three major functions within metalloproteins to provide structural support, to serve as enzymatic cofactors, and to mediate electron transportation. Metal ions are also involved in the immune system from metal allergies to nutritional immunity. Within the past decade, much attention has been drawn to the roles of metal ions in the immune system, since increasing evidence has mounted to suggest that metals are critically implicated in regulating both the innate immune sensing of and the host defense against invading pathogens. The importance of ions in immunity is also evidenced by the i, in order to draw a general diagram of metalloimmunology. © 2020 Elsevier Inc.

The engagement of these receptors transmits intracellular signaling mainly by recruiting SLAM-associated protein (SAP) and its related adaptors, EWS-FLI1-activated transcript-2 (EAT-2) and EAT-2-related transducer (ERT). The critical roles of SFRs and SAP-family adaptors are highlighted by the discovery that SAP is mutated in human X-linked lymphoproliferative (XLP1) disease in which the contact between T and B cells in germinal center and cytotoxic lymphocytes (NK cells and CD8+ T cells) function are severely compromised. These immune defects are closely associated with the defective antibody production and the high incidence of lymphoma in the patients with XLP1. In addition to these well-known functions, SLAM-SAP family is involved in NK cell education, a process describing NK cell functional competence.
