We explored the frequency of CD14- CD10- CD45+ HLA-DR- SSC++ neutrophils (CD10- neutrophils) in patients with non-Hodgkin's lymphoma (NHL), and their immunologic characteristics and clinical significance. Patients with NHL who were newly diagnosed (NDP; n = 33), in remission (RMP; n = 28) and relapsed (RLP; n = 29) were included, and 47 volunteers were recruited as healthy controls (HCs). The frequency of CD10- neutrophils in the peripheral blood from HC and patients with NHL was detected...

CD4+ forkhead box P3 (FOXP3)+ regulatory T cells (Tregs) are essential in maintaining immune tolerance and suppressing excessive immune responses. Tregs also contribute to tissue repair processes distinct from their roles in immune suppression. For these reasons, Tregs are candidates for targeted therapies for inflammatory and autoimmune diseases, and in diseases where tissue damage occurs. MT-2 cells, an immortalized Treg-like cell line, offer a model to study Treg biology and their therapeutic potential. In the present study, we use clustered regularly interspaced palindromic repeats (CRISPR)-mediated knockdown of FOXP3 in MT-2 cells to understand the transcriptional and functional changes that occur when FOXP3 is lost and to compare MT-2 cells with primary human Tregs...

T helper 2 (Th2) cells stochastically express from the Il4 locus but it has not been determined whether allelic expression is linked or independent. Here, we provide evidence that alleles are independently activated and inactivated. We compared Il4 locus expression in T cells from hemizygous IL-4 reporter mice in culture and in vivo following exposure to type 2 immunogens. In culture, Il4 alleles had independent, heritable expression probabilities. Modeling showed that in co-expressors, dual allele transcription occurs for only short periods, limiting per-cell mRNA variation in individual cells within a population of Th2 cells...

Therapy-induced senescence (TIS) is a primary response to chemotherapy, contributing to untoward treatment outcomes such as evasion of immunosurveillance. Despite the established role of the complement system in the immune response to cancer, the role of complement in mediating the immune response against senescent tumor cells remains poorly understood. To explore this relationship, we exposed lung adenocarcinoma (A549), breast adenocarcinoma (MCF7) and pancreatic carcinoma (Panc-1) cell lines to sublethal doses of either etoposide or doxorubicin to trigger TIS...

In this article, we discuss a recently published article that demonstrated a novel way of identifying viral pathogens reactivating in human cells to be used as cellular therapy, in this instance chimeric antigen receptor (CAR) T cells. The authors used search engines and databases to identify viruses able to reactivate in T cells and then tested this initially in T-cell cultures, specifically human herpesvirus 6. This virus was then shown to reactivate infrequently in vitro and in vivo in CAR T cells as a consequence of T-cell activation...

Cancer immunotherapy has been rejuvenated by the growing understanding of the immune system's role in tumor activity over the past two decades. During cancer initiation and progression, tumor cells employ various mechanisms that resemble peripheral immune tolerance to evade the antitumor responses of the immune system. Immune checkpoint molecules are the major mechanism of immune resistance that are exploited by tumor cells to inhibit T-cell activation and suppress immune responses. The targeting of immune checkpoint pathways has led to substantial improvements in survival rates in a number of solid cancers...

Vimentin, an intermediate filament protein primarily recognized for its intracellular role in maintaining cellular structure, has recently garnered increased attention and emerged as a pivotal extracellular player in immune regulation and host-pathogen interactions. While the functions of extracellular vimentin were initially overshadowed by its cytoskeletal role, accumulating evidence now highlights its significance in diverse physiological and pathological events. This review explores the multifaceted role of extracellular vimentin in modulating immune responses and orchestrating interactions between host cells and pathogens...

The cellular complexity of the endochondral bone underlies its essential and pleiotropic roles during organismal life. While the adult bone has received significant attention, we still lack a deep understanding of the perinatal bone cellulome. Here, we have profiled the full composition of the murine endochondral bone at the single-cell level during the transition from fetal to newborn life and in comparison with the adult tissue, with particular emphasis on the mesenchymal compartment. The perinatal bone contains different fibroblastic clusters with blastema-like characteristics in organizing and supporting skeletogenesis, angiogenesis and hematopoiesis...

As part of the Monash Sensory Science Exhibition, our team guided participants through a multisensory journey unraveling coeliac disease development and pathology. Through tactile and sensory exhibits, we showed how benign dietary gluten can be transformed into a harmful entity for the 1 in 70 Australians with this illness. In contrast to the common misconception of coeliac disease as a food allergy, our exhibits revealed its closer association with autoimmune diseases such as type 1 diabetes, involving genetic susceptibility linked to specific human leukocyte antigens, crucial antigen-specific T- and B-cell responses and autoantibody production...

Programmed death receptor 1 (PD-1) is an inhibitory receptor on T cells shown to restrain T-cell proliferation. PD-1 immune checkpoint blockade has emerged as a highly promising approach in cancer treatment. Much of our understanding of the function of PD-1 is derived from in vitro T-cell activation assays. Here we set out to further investigate how T cells integrate inhibitory signals such as PD-1 in vitro using the PD-1 agonist, PD-1 ligand 1 (PD-L1) fusion protein (PD-L1.Fc), coimmobilized alongside anti-CD3 agonist monoclonal antibody (mAb) on plates to deliver PD-1 signals to wild-type and PD-1-/- CD8+ T cells...

Reducing the activity of cytokines and leukocyte extravasation is an emerging therapeutic strategy to limit tissue-damaging inflammatory responses and restore immune homeostasis in inflammatory diseases. Proteoglycans embedded in the vascular endothelial glycocalyx, which regulate the activity of cytokines to restrict the inflammatory response in physiological conditions, are proteolytically cleaved in inflammatory diseases. Here we critically review the potential of proteolytically shed, soluble vascular endothelial glycocalyx proteoglycans to modulate pathological inflammatory responses...

Scientific outreach activities play an important role in disseminating knowledge, connecting the general public to research and breaking down scientific skepticism barriers. However, the vision-impaired community is often disadvantaged when the most common audio-visual approach of scientific communication is applied. Here we integrated tactile clues in the scientific communication of immune processes involved in the autoimmune skin disease psoriasis. We fostered the involvement of the vision-impaired community through interactive experiences, including tactile scientific origami art, a haptic poster and wood-carved molecular models...

The advent and clinical success of immune checkpoint inhibitors Ipilimumab, Nivolumab and Pembrolizumab has had a seismic impact on our drug discovery focus and rationale. Novel extrinsic targets that enhance immune responses to cancer are actively being pursued, while tumor intrinsic targets that render cancer cells more sensitive to the immune system have joined traditional intrinsic targets (e.g. directly cytotoxic) in the drug discovery pipeline. The phosphatase PTPN2 (TC-PTP) and its paralog PTPN1 (PTP-1B) are negative regulators of several cytokine signaling pathways and T cell receptor (TCR) signaling...

The biology of the NACHT domain and leucine-rich repeat (NLR) and pyrin domain-containing 1 (NLRP1) inflammasome has perplexed researchers since this inflammasome was first described about two decades ago. The identification of oxidized thioredoxin 1 (TRX1) as a suppressor of NLRP1 recently linked cellular redox homeostasis to NLRP1 inflammasome signaling. Now, Zhang et al. present a molecular structure of TRX1-bound NLRP1 with unprecedented detail. This structure gives key insight into regulatory mechanisms governing NLRP1 activation and offers enormous potential for structure-based anti-inflammatory drug design...

Immunology for all: Most scientific communication has historically been limited to visual imagery and the written or spoken word, often in the form of dense articles obscured by jargon. Clear communication of science is vital to enable the public to engage with important scientific discoveries and to limit medical distrust. However, scientific communication is often executed in a way which neglects people with blindness, low vision and diverse needs. Our aim for the exhibit at the Monash Sensory Science Exhibition on Autoimmunity 2023 at Monash University was to develop novel, tactile and informative models to help better communicate the scientific principles that underpin autoimmune disease and immunology...
