Summary: Regulation of proinflammatory cytokine expression is crucial in ssRNA virus infections. IL-27 has a modulatory role on TLR7 and TLR8 responses, enhancing TLR7 expression and TLR8-mediated cytokine secretion. Additionally, TLR7 agonist can inhibit cytokine and chemokine production induced by a TLR8 agonist.

Summary: The expression of IL-22R1 on blood myeloid cells and CD4(+) T lymphocytes is abnormal in SARS-CoV-2 infection, and it may have protective effects at the beginning of the infection but become detrimental over time.

Summary: The study demonstrates that IDO1 affects the recruitment of immune cells by inhibiting DCs maturation and subsequent T cell proliferation, exacerbating the progression of liver fibrosis. Targeting IDO1 to ameliorate immune responses in the hepatic and splenic microenvironment may be essential for therapeutic effects on liver fibrosis.

Summary: Atherosclerosis is a chronic disease characterized by damage to the intima, inflammatory cell recruitment, and lipid accumulation followed by calcification and plaque rupture. Inflammation is believed to play a crucial role in the development and progression of the disease. This paper discusses the various types of inflammatory cells involved in atherosclerosis and their significance in the disease's development and progression. Understanding the role of these cells at different stages of the disease provides valuable insights for targeted therapy.

Summary: IL-37 is released following the activation of the canonical and alternative NLRP3 inflammasomes. The study proposes a novel pathway in which IL-37 is cleaved by caspase-1-independent mechanisms and released through differential pathways.

Summary: Our study identified a novel mutation c.1715G>T (p.G572V) in the Toll-like receptor 8 (TLR8) gene, which causes an autoimmune and autoinflammatory disorder in a family with monozygotic male twins. In vitro assays confirmed the pathogenicity of the mutation and revealed increased inflammatory responses.

Summary: The study showed that anti-TLR7 monoclonal antibody protected lupus-prone mice from nephritis by reducing IgG deposition in glomeruli through inhibiting autoantibody production. In addition, the antibody also suppressed the increase of lupus-associated patrolling monocytes in circulation, spleen, and glomeruli. These findings suggest that targeting TLR7 could be a promising therapeutic approach for lupus nephritis by regulating autoantibody production and monocytosis.

Summary: This study investigates whether TLRs other than TLR4 can initiate the alternative NLRP3 inflammasome pathway and finds that TLR1/2, TLR2/6, TLR4, and TLR7 and/or TLR8 can induce the release of IL-1 beta in primary human monocytes, independent of K+ efflux and pyroptosis.

Summary: This study demonstrates that repetitive TLR7 stimulation can induce an emergency bone marrow monocyte response, independent of the canonical CCR2 and CX3CR1 axes or prototypical cytokines. The monocytes released from the bone marrow differentiate into monocytes and macrophages in multiple organs, and display a reduced cytokine response to further TLR7 stimulation, leading to reduced lung viral load after RSV and influenza virus infection.

Summary: Plasmacytoid dendritic cells (pDCs) in women produce higher levels of TLR7-driven type I interferon during HIV-1 infection, leading to stronger antiviral responses compared to men. However, excessive TLR7 response in women has been found to have a deleterious impact on acute viremia. This is attributed to specific genetic variations in TLR7 which affect protein synthesis and effector function, resulting in lower viral load during primary HIV-1 infection in females.

Summary: TLR7 and TLR8 play crucial roles in innate immunity and can be therapeutic targets for diseases like infections and cancer. The biological response to small molecule binding differs between TLR7 and TLR8. Through molecular dynamic simulations and binding free energy calculations, it was found that selective agonists were more favorable for TLR7. Van der Waals interactions were identified as the driving force for agonist binding.

Summary: A series of previously unknown 5,14-diphenylbenzo[j]naphtho[2,1,8-def][2,7]phenanthrolines, incorporating a 5-azatetracene and a 2-azapyrene subunit, were successfully synthesized using Pd-catalyzed cross-coupling reactions and a one-pot Povarov/cycloisomerization reaction. This synthetic approach enables extensive diversification of the heterocyclic core structure. The optical and electrochemical properties of these compounds were investigated through experimental and computational studies, revealing their closer electronic and optical resemblance to 2-azapyrenes rather than the typical characteristics of 5-azatetracene moieties.

Summary: In this second part of the comprehensive review on the optimization of reverse shoulder arthroplasty (RSA), three other challenges are focused on: 1. Conservation of sufficient subacromial and coracohumeral space; 2. Scapular posture; and 3. Moment arms and muscle tensioning. The implications of these challenges are essential to optimize RSA function and improve active force generation. Understanding and addressing these challenges can help prevent complications and guide further research in the field of RSA optimization.

Summary: Two review articles present a detailed overview of the challenges in optimizing reverse shoulder arthroplasty (RSA) based on the basic science and clinical literature. These challenges include external rotation and extension, internal rotation, subacromial and coracohumeral space preservation, scapular posture, moment arms, and muscle tensioning. It is crucial to define criteria and algorithms for planning and executing optimized, balanced RSA to improve range of motion, function, and longevity while minimizing complications.

Summary: This systematic review and meta-analysis compared resurfacing hip arthroplasty (RHA) and total hip arthroplasty (THA) in terms of complications, revisions, functional outcomes, blood loss, operative time and metal ions levels. The findings showed that RHA had significantly lower blood loss but longer operative time compared to THA. There was no significant difference in complications, revisions, functional outcomes, and metal ion levels between RHA and THA. Both RHA and THA were found to be safe and effective, with RHA being a valid alternative to THA in young and active patients.

Summary: Gastrointestinal stromal tumors (GISTs) frequently show KIT mutations, leading to overexpression and abnormal localization of mutant KIT (MT-KIT). BLZF1 was identified as a novel binding partner of MT-KIT, anchoring it to the Golgi complex. The sustained activation of ATF6, a member of the unfolded protein response (UPR) family, helps in MT-KIT folding and relieves endoplasmic reticulum (ER) stress. The activation of ATF6 is frequently observed in GIST patients and is significantly associated with poorer relapse-free survival.

Summary: RNA variants resulting from cancer-associated RNA editing events can serve as a potential source of neoantigens. The authors use a comprehensive proteogenomic pipeline to identify and validate neoantigen candidates in patients with different tumor types, highlighting the importance of RNA as a significant source of neoantigens. Systemic pan-tumor analyses can provide insights into common features associated with cancer immunogenicity and patient survival.
