Cd7 Regulates The Persistence Of Terminally Exhausted Cd8 T Cells During Chronic Infection, Sean Hyslop, Colby J Hofferek, Maria V Stegantseva, Emerald Kan, Kelli A Mccord, Victor M Alvarez, Amanda Y Xia, Jacob P Conarty, Andreas Wieland, William H Hudson

Faculty, Staff and Students Publications

CD8+ T cell exhaustion limits immune responses during cancer and chronic infection. We identify CD7 as a tissue-specific regulator of terminally exhausted CD8+ T cells during chronic infection. CD7 expression progressively increases during exhaustion, reaching its highest levels on a subset of CD101+Tim3low terminally exhausted cells that arise in the liver. Transcriptomic analysis revealed that CD7-deficient terminally exhausted cells display altered expression of co-stimulatory, translational, and effector genes, correlating with markedly reduced persistence and increased apoptotic susceptibility. Importantly, CD7 is preferentially upregulated on PD-1+CD39+ tumor-infiltrating lymphocytes (TILs) in human head and neck squamous cell carcinoma (HNSCC), suggesting CD7 may play …

Faculty, Staff and Students Publications

Background: Real-world data on the benefit of high-dose inhaled corticosteroid (ICS) post-exacerbation are limited.

Objective: To investigate whether stepping-up to high-dose inhaled corticosteroid (ICS) post-severe exacerbation reduces future asthma exacerbation risk in a real-world setting.

Methods: This was a retrospective cohort study using the Optum® Clinformatics® database (October 2015-December 2023). Patients with asthma, aged ≥12 years, with ≥1 severe exacerbation and ≥2 ICS maintenance prescriptions in the 12-months pre-, and ≥1 ICS maintenance prescription in the 3-months post-exacerbation were included. Primary and secondary endpoints were annualized asthma exacerbation rate (AAER) and time to first subsequent severe exacerbation, respectively. We compared …

Modeling The Effects Of Screening, Vaccination, Treatment, And Non-Pharmaceutical Controls On Leptospirosis Transmission Dynamics, Janeth Michael, Herieth Rwezaura, Goodluck Mlay, Nyimvua Shaban Mbare

Tanzania Journal of Science

Leptospirosis is the world’s most common zoonotic disease and remains a significant public health challenge, particularly in regions with poor sanitation and high exposure risks. This study aims to evaluate the effectiveness of combined interventions: screening, vaccination, treatment, and non-pharmaceutical controls in reducing leptospirosis transmission in human and domestic animal populations. The study develops and analyzes a deterministic compartmental model with eleven compartments representing human, domestic animal, and bacterial populations. Stability analysis reveals that the Disease-Free Equilibrium (DEF) is globally asymptotically stable when the effective reproduction number is less than a unit ( < 1), ensuring disease eradication under these conditions, whereas the Endemic Equilibrium Point (EEP) remains stable when > 1. The study employs the normalized forward …

Evaluating Weather Research And Forecasting Model In Simulating March-May Rainfall In Tanzania: Implications Of Selecting Parameterization Schemes, Mohamed H. Mohamed, Makungu James Ng'oga

Tanzania Journal of Science

The current study evaluates the performance of the Weather Research and Forecasting (WRF) model in simulating seasonal rains of March-May (MAM) in Tanzania, based on the implication of selecting parameterization scheme combinations. The model was configured into two domains with horizontal resolutions of 36 km and 12 km and the initial and lateral boundary conditions were provided by the Climate Forecast System Version 2 at 00 UTC. However, only the inner domain of 12 km was used for analysis, which has a fine horizontal resolution that accounts for small scale features such as terrains. Twelve simulations have been performed using …

Formation And Dramatic Significance Of The “Separation” System In Ming Dynasty Southern Opera Scripts, Zhiyong Chen

Theoretical Studies in Literature and Art

The practice of “fenchu” (separation) marks a pivotal development in the Ming dynasty's chuanqi playwriting system, manifesting as either “implicit” or “explicit” separation within early Southern Opera texts. The late Ming period saw enhancements in the separation methodologies within actors' performance manuscripts and reader-oriented printed editions, improving upon the character entry and exit strategies from the Song, Yuan, and early Ming operas. This led to the formulation of separation standards that reconcile character transitions, scene consistency, and narrative cohesion. The emergence of the separation mechanism in Southern Opera is attributed to multifaceted causes: for performance scripts, it facilitated …

The Movement For The Popularization Of Literature And Art: Development And Transformation, Yanqiu Zhao

Theoretical Studies in Literature and Art

The major issues and fundamental perspectives concerning the popularization of literature and art can be broadly categorized into six aspects: the direction of development, the object of service, the subject of creation, the content and form, the language, and the evaluation of the May Fourth and New Culture Movements. While the theory and practice of the popularizing literature and art hold positive significance, they are also subject to biases and limitations. Mao Zedong, rather than merely perpetuating the ideals and objectives of the movement, deconstructed, synthesized and reformed its content and issues. He proposed his own insights and solutions to …
