Avidity of influenza-specific memory CD8+ T-cell populations decays over time compromising antiviral immunity [PDF]

, 2012
Decline of cell-mediated immunity is often attributed to decaying T-cell numbers and their distribution in peripheral organs. This study examined the hypothesis that qualitative as well as quantitative changes contribute to the declining efficacy of CD8+

Natural killer cell responses during SARS-CoV-2 infection and vaccination in people living with HIV-1

Scientific Reports, 2023
Natural killer (NK) cell subsets with adaptive properties are emerging as regulators of vaccine-induced T and B cell responses and are specialized towards antibody-dependent functions contributing to SARS-CoV-2 control.

State Immunity and Judicial Countermeasures [PDF]

, 2021
This article explores whether domestic courts can deny jurisdictional immunity of a state as a countermeasure. The article offers a survey of state practice that, according to some scholars, would support this argument, demonstrating that the ...

The Role of Capsid in the Early Steps of HIV-1 Infection: New Insights into the Core of the Matter

Viruses, 2021
In recent years, major advances in research and experimental approaches have significantly increased our knowledge on the role of the HIV-1 capsid in the virus life cycle, from reverse transcription to integration and gene expression.

The long subclinical phase of Mycobacterium avium ssp. paratuberculosis infections explained without adaptive immunity [PDF]

, 2015
Mycobacterium avium ssp. paratuberculosis (MAP) is an infection of the ruminant intestine. In cows, a long subclinical phase with no or low intermittent shedding precedes the clinical phase with high shedding.

Immune Dysregulation in Immune Thrombocytopenia [PDF]

Seminars in Hematology, 2013
Immune thrombocytopenia (ITP) is a bleeding disorder characterized by low platelet counts due to decreased platelet production as well as increased platelet destruction by autoimmune mechanisms. A shift toward Th1 and possibly Th17 cells together with impaired regulatory compartment, including T-regulatory (Tregs) and B-regulatory (Bregs) cells, have ...

Exploring the pre-immune landscape of antigen-specific T cells

Genome Medicine, 2018
Background Adaptive immune responses to newly encountered pathogens depend on the mobilization of antigen-specific clonotypes from a vastly diverse pool of naive T cells.

Ex vivo engineered human plasma cells exhibit robust protein secretion and long-term engraftment in vivo

Nature Communications, 2022
Plasma B cells (PC) are a potential source for protein replacement as they could be engineered to secrete protein other than antibody. Here the authors engineer B cells to express exogenous proteins and demonstrate that these cells can persist long term ...

Experimental cerebral malaria develops independently of caspase recruitment domain-containing protein 9 signaling.

, 2011
The outcome of infection depends on multiple layers of immune regulation, with innate immunity playing a decisive role in shaping protection or pathogenic sequelae of acquired immunity.
