Herpes zoster (HZ) is an infectious dermatosis with high incidence worldwide. Age is a key risk factor for HZ, and postherpetic neuralgia (PHN) is the main sequelae. Until now, no index has been available to predict the pathogenesis of PHN, and rare reports have focused on the immune response during aging and PHN. In this study, we selected immunoglobulin and complement proteins as markers for humoral immunity, while T lymphocyte subsets and natural killer (NK) cells were selected as markers for cell immunity, to systematically study the characteristics of immune responses in the peripheral blood of HZ patients. Our data showed that the absolute number of CD3 T cells and CD8 T cells decreased during aging and PHN. This implies that more attention should be paid to prevent the occurrence of PHN, especially in the aged population.

Background: CD3 + CD20 + T cells (T cells) are a subset of lymphocytes in the human body that are associated with inflammation. They originate from T cells interacting with B cells, and their levels are abnormally elevated in individuals with immune disorders, as well as in some cancer patients. The interplay between tumor immunity and inflammation is intricate, yet the specific involvement of T cells in local tumor immunity remains uncertain, with limited research on their subtypes.

T-cell clonality assessment constitutes an essential part of the diagnostic evaluation of suspected T-cell neoplasms. Recent advances in flow cytometry-based analysis of TCR β chain constant region 1 (TRBC1) have introduced an accurate method of assessment of T-cell clonality. Its broader applicability is constrained due to the requirement of viable cells.

Compelling evidence suggests a significant association between antibody-mediated immune responses and multiple sclerosis (MS). However, the exact causal relationships between these immune responses and MS remain unclear. In this study, we conducted a comprehensive examination of the link between antibody-mediated immune responses and MS via Mendelian randomization (MR) analysis to identify specific infectious pathogens potentially involved in the onset and progression of MS.

The prognosis for patients with melanoma loco-regional metastases is very heterogenous. Adjuvant PD-L1-inhibitors have improved clinical outcome for this patient group, but the prognostic impact of tumour PD-L1 expression and number of tumour infiltrating lymphocytes (TILs) is still largely unknown. Here, we investigated the impact on survival for CD3, CD8, FOXP3 and PD-L1 TIL counts and tumour PD-L1 expression in melanoma loco-regional metastases.

Background: Hypoxia in tumor cells is linked to increased drug resistance and more aggressive behavior. In pancreatic cancer, the tumor microenvironment is notably hypoxic and exhibits strong immunosuppressive properties. Given that immunotherapy is now approved for pancreatic cancer treatment, further understanding of how pancreatic tumor cell hypoxia influences T-cell cytotoxicityis essential.
