Background: Clonal mature B-cell lymphoproliferative disorders (B-LPDs) are a heterogeneous group of neoplasia characterized by the proliferation of mature B lymphocytes in the peripheral blood, bone marrow and/or lymphoid tissues. B-LPDs classification into different subtypes and their diagnosis is based on a multiparametric approach. However, accurate diagnosis may be challenging, especially in cases of ambiguous interpretation.

How changes in the quality of anti-viral antibody (Ab) responses due to pre-existing or acquired CD4 T cell insufficiency affect virus evolution during persistent infection are unknown. Using mouse polyomavirus (MuPyV), we found that CD4 T cell depletion before infection results in short-lived plasma cells secreting low-avidity antiviral IgG with limited BCR diversity and weak virus-neutralizing ability. CD4 T cell deficiency during persistent infection incurs a shift from a T-dependent (TD) to T-independent (TI) Ab response, resembling the pre-existing TI Ab response.

Cytomegalovirus is a promising vaccine vector; however, mechanisms promoting CD4 T cell responses to challenge, by CMV as a vector, are unknown. The ability of MCMV to prolong immunity generated by short-lived malaria vaccine was tested. MCMV provided non-specific protection to challenge with and increased interleukin-12 (IL-12) and CD8α dendritic cell (DC) numbers through prolonged MCMV-dependent interferon gamma (IFN-γ) production.

Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus-associated disease, clinically resulting in immunosuppression and co-infections with other pathogens in infected pigs. The mechanism of PCV2 infection remains unclear. In this study, we firstly found that the tetraspanin CD81 in PK-15 cells interacts with PCV2 Cap protein by using virus overlay protein-binding assay combined with mass spectrometry.

Article Synopsis
- Memory-phenotype (MP) CD4 T lymphocytes develop from naïve T cells and can differentiate into various T cell subsets to manage inflammation, especially in low-immune settings.
- The study highlights that MP lymphocytes are not only made up of T helper 1 (T1) and T helper 17 (T17) cells but also contain a "undifferentiated" subpopulation that has the potential to develop into these functional subsets.
- The undifferentiated MP lymphocytes possess the ability to proliferate rapidly and can differentiate into T1, T17, and regulatory T cells, which contributes to inflammation, although their response is regulated by existing T cells.
