The early human interferon gamma response to is driven by Vγ9Vδ2 T-cell sensing of host phosphoantigens and subsequent NK-cell activation.

is a globally prevalent intracellular parasite that infects ~40 million Americans. The murine immune response to relies on both toll-like receptor (TLR) 11/12 and immunity related GTPase-mediated (IRGs) responses, which humans lack, making it unclear how the human immune response detects and responds to the parasite. We investigated whether human Vγ9Vδ2 T cells, which detect phosphoantigens through the BTN3A1 receptor, shape the early immune response to the parasite.

Autophagy controls differentiation of Drosophila blood cells by regulating Notch levels in response to nutrient availability.

Drosophila larval hematopoiesis takes place at the lymph gland, where blood cell progenitors differentiate into two possible cell types: Plasmatocytes, analogous to mammalian macrophages, or crystal cells that share features with mammalian megakaryocytes; a third cell type, the lamellocytes, develop only upon specific immune challenges. Here we show that autophagy inhibition in blood cell progenitors results in augmented crystal cell differentiation due to Notch accumulation. Notch activation during hematopoiesis depends on the endocytic pathway, which crosstalks with autophagy: While Notch activation depends on endocytosis and endosomal maturation, Notch lysosomal degradation requires autophagy.

Ligand-lytic peptides for specific targeting of and parasites.

Introduction: Leishmaniasis and Chagas disease are major human neglected diseases, affecting an estimate of 12 and 6 to 8 million people worldwide, respectively. Current treatments for both diseases are highly toxic for the vertebrate host and lack specificity for the parasites, highlighting the need for the discovery of new therapies against these diseases. In this study, we tested the use of the lytic peptide and a construct that incorporates a ligand to bind the lytic peptide to protozoa membranes and screened them for protozoacidal activity.

Link of TMPRSS2 expression with tumor immunogenicity and response to immune checkpoint inhibitors in cancers.

Background: SARS-CoV-2 and other viruses rely on the protease function of the TMPRSS2 protein to invade host cells. Despite cancer patients often experience poorer outcomes following SARS-CoV-2 infection, the role of TMPRSS2 in different cancer types has not yet been analyzed in detail. Therefore, the aim of the study was to determine the expression, function and clinical relevance of TMPRSS2 in tumors.

Quality of life following perioperative optimization with nutritional supplements in patients undergoing gastrointestinal surgery for cancer: A randomized, placebo-controlled feasibility clinical trial.

Background: Up to two thirds of patients presenting for abdominal cancer surgery are malnourished pre-operatively. Perioperative nutritional supplementation has been proposed to improve surgical outcomes, though its effect on quality of life (QoL) is not yet understood.

Methods: A randomized controlled feasibility trial for perioperative nutrition among patients undergoing major abdominal cancer surgery was conducted.

Genome-wide CRISPR screen identifies genes synthetically lethal with GRA17, a nutrient channel encoding gene in Toxoplasma.

Toxoplasma gondii is a parasite that replicates within a specialized compartment called the parasitophorous vacuole (PV), which is surrounded by the PV membrane (PVM). To obtain essential nutrients, Toxoplasma must transport molecules across the PVM, a process mediated by the secreted parasite proteins GRA17 and GRA23. These proteins form pores in the PVM through which small molecules can diffuse in and out of the PV.

Variation in CD8 T cell IFNγ differentiation to strains of is characterized by small effect QTLs with contribution from ROP16.

Introduction: induces a strong CD8 T cell response characterized by the secretion of IFNγ that promotes host survival during infection. The initiation of CD8 T cell IFNγ responses differs widely between clonal lineage strains of , in which type I strains are low inducers, while types II and III strains are high inducers. We hypothesized this phenotype is due to a polymorphic "Regulator Of CD8 T cell Response" (ROCTR).

What does the public think about microplastics? Insights from an empirical analysis of mental models elicited through free associations.

Microplastics are an issue of rising concern, in terms of their possible implications for both the environment and human health. A survey was distributed among a representative sample of the adult Norwegian population ( = 2720) to explore the public understanding of microplastics. Respondents were asked to report the first thing that came to mind when they read or heard the word "microplastics," based on which a coding scheme was developed that served to categorize the obtained answers into thematic clusters.

Critical Incidences in U.S. Health Care Systems Experienced by Undocumented Young Adults.

Undocumented ("illegal immigrant") young adults and families face many barriers when seeking health care, including discrimination, which contributes to health disparities. Using critical race theory, an investigation of experiences of health care among undocumented young adults was conducted to highlight their limitations to health care access. Using a community-based participatory paradigm, a qualitative research approach was used to explore the experiences of 13 participants via a semistructured interview.

The causative agent of Chagas disease, Trypanosoma cruzi, is transmitted by triatomine vectors. The insect is endemic in the Americas, including the United States, where epidemiological studies are limited, particularly in the Southwestern region. Here, we have determined the prevalence of T.

Lymphatic Proliferation Ameliorates Pulmonary Fibrosis after Lung Injury.

Despite many reports about pulmonary blood vessels in lung fibrosis, the contribution of lymphatics to fibrosis is unknown. We examined the mechanism and consequences of lymphatic remodeling in mice with lung fibrosis after bleomycin injury or telomere dysfunction. Widespread lymphangiogenesis was observed after bleomycin treatment and in fibrotic lungs of prospero homeobox 1-enhanced green fluorescent protein (Prox1-EGFP) transgenic mice with telomere dysfunction.

Naïve CD8 T cell IFNγ responses to a vacuolar antigen are regulated by an inflammasome-independent NLRP3 pathway and Toxoplasma gondii ROP5.

Host resistance to Toxoplasma gondii relies on CD8 T cell IFNγ responses, which if modulated by the host or parasite could influence chronic infection and parasite transmission between hosts. Since host-parasite interactions that govern this response are not fully elucidated, we investigated requirements for eliciting naïve CD8 T cell IFNγ responses to a vacuolar resident antigen of T. gondii, TGD057.

and Characterization of Potent Antileishmanial Methionine Aminopeptidase 1 Inhibitors.

is the causative agent of cutaneous leishmaniasis (CL). No human vaccine is available for CL, and current drug regimens present several drawbacks, such as emerging resistance, severe toxicity, medium effectiveness, and/or high cost. Thus, the need for better treatment options against CL is a priority.

Background: The marine alga Ulva compressa is the dominant species in copper-polluted coastal areas in northern Chile. It has been shown that the alga tolerates micromolar concentrations of copper and accumulates copper at the intracellular level. Transcriptomic analyses were performed using total RNA of the alga cultivated with 10 μ M copper for 0, 1, 3 and 5 days using RNA-seq in order to identify processes involved in copper tolerance.

Traumatic esophageal perforation in Puerto Rico Trauma Hospital: A case-series.

Background: Esophageal injuries are rare, life-threatening, events with an overall reported incidence of less than 3%. In rare cases, trauma due to blunt or penetrating injuries cause esophageal perforations, which account for less than 15% of all esophageal injuries.

Materials And Methods: A case-series study was conducted to describe the outcomes and management of all the traumatic esophageal injuries at the Puerto Rico Trauma Hospital (PRTH) from 2000 through 2017.

Treatment of Hidradenitis Suppurativa with Extensive Resection of the Lesion and Coverage with Perforator Flaps of the Lateral Thoracic Wall (Lateral Thoracic Artery, Thoracodorsal Artery Perforators).

Stage IV hidradenitis suppurativa in the axilla is a chronic disease in which the removal of the affected area and a reconstruction with disease free skin is the definitive treatment; however there is some controversy about the technique to be used in this reconstruction. Studies show superiority in wide resections, and coverage with flaps rather than grafts. The use of pedicle flaps of lateral thoracic artery perforators and thoracodorsal artery perforators has demonstrated superior performance to other techniques in postsurgical follow-up.
