Distributable, Metabolic PET Reporting of Tuberculosis

This paper introduces [18F]FDT, a PET tracer that specifically images Mycobacterium tuberculosis lesions and monitors treatment, enabling global access through a simple synthesis method from [18F]FDG.

IL-10 suppresses T cell expansion while promoting tissue-resident memory cell formation during SARS-CoV-2 infection in rhesus macaques

This study examines the roles of IFNγ and IL-10 in SARS-CoV-2 infection of rhesus macaques, finding IL-10 suppresses T cell expansion but promotes tissue-resident memory cell formation.

Intranasal pediatric parainfluenza virus-vectored SARS-CoV-2 vaccine candidate is protective in macaques

This study evaluates an intranasal parainfluenza virus-vectored SARS-CoV-2 vaccine in macaques, showing it induces mucosal and systemic immunity and protects against viral challenge.

Rapid GPR183-mediated recruitment of eosinophils to the lung after Mycobacterium tuberculosis infection

This study shows that eosinophils migrate to the lungs early after Mycobacterium tuberculosis infection in mice and macaques, mediated by GPR183 and Ch25h, independent of CCR3.

Mild SARS-CoV-2 infection in rhesus macaques is associated with viral control prior to antigen-specific T cell responses in tissues

This study shows that SARS-CoV-2 replication declines in the lungs before T cell responses, while innate immunity restricts viral replication in nasal and oral mucosa in rhesus macaques.

CD4 T cells are rapidly depleted from tuberculosis granulomas following acute SIV co-infection

This study shows that acute SIV co-infection rapidly depletes CD4 T cells from tuberculosis granulomas before systemic CD4 T cell loss or disease reactivation.

Eosinophils are an integral component of the pulmonary granulocyte response in Tuberculosis and promote host resistance in mice

This study shows eosinophils are recruited to tuberculosis-infected lung tissue in mice and contribute to host resistance against Mtb infection.

Functional inactivation of pulmonary MAIT cells following 5-OP-RU treatment of non-human primates

This study shows that 5-OP-RU treatment of M. tuberculosis-infected rhesus macaques leads to MAIT cell dysfunction rather than expansion, with upregulated PD-1 and loss of cytokine production.

PD-1 blockade exacerbates Mycobacterium tuberculosis infection in rhesus macaques

This study shows that PD-1 blockade worsens Mycobacterium tuberculosis infection in rhesus macaques by increasing bacterial loads and altering immune responses.
