Article Title: Progesterone Modulation of Pregnancy-Related Immune Responses
Article Snippet: Finally, the development step required the use of a chromogen prepared from a premixed BCIP/NBT substrate kit (BioRad labouratories Ltd., Hertfordshire, UK). .. Spot reading and counting was performed using an AID ELISpot reader (Oxford Biosystems Cadama, Oxfordshire, UK). ..

Article Title: Detection of Hepatic Drug Metabolite-Specific T-Cell Responses Using a Human Hepatocyte, Immune Cell Coculture System.
Article Snippet: The enzyme-linked immunospot (ELISpot) assay was employed to evaluate secretory molecules (IFN-γ, granzyme B, IL-5, perforin, IL-13, IL-17, IL-22, and Fas-L) released by clones upon challenge with the parent drug and metabolite. .. Plates were precoated with the target capture antibody for 24 h, cocultures (5 × 104 T-cell clones and 1 × 104 irradiated autologous EBV-transformed B-cells) were incubated in the presence of media, dapsone, or nitroso dapsone at various concentrations for 48 h.

Article Title: Pregnancy-related immune suppression leads to altered influenza vaccine recall responses.
Article Snippet: Pregnancy is a risk factor for severe influenza infection.. Despite achieving seroprotective antibody titres post immunisation fewer pregnant women experience a reduction in influenza-like illness compared to non-pregnant cohorts.. This may be due to the effects that immune-modulation in pregnancy has on vaccine efficacy leading to a less favourable immunologic response.

Article Title: Shedding Light on Drug-Induced Liver Injury: Activation of T Cells From Drug Naive Human Donors With Tolvaptan and a Hydroxybutyric Acid Metabolite.
Article Snippet: Exposure to tolvaptan is associated with a significant risk of liver injury in a small fraction of patients with autosomal dominant polycystic kidney disease.. The observed delayed onset of liver injury of between 3 and 18 months after commencing tolvaptan treatment, along with rapid recurrence of symptoms following re-challenge is indicative of an adaptive immune attack.. This study set out to assess the intrinsic immunogenicity of tolvaptan and pathways of drugspecific T-cell activation using in vitro cell culture platforms.

(C) Magnitude of IFNγ+, IFNγ+TNF+, and CTV lo IFNγ+ CD4 and CD8 T cells after 8-day expansion with a pool of 12 peptides corresponding to ancestral sequence epitopes or variant sequence epitopes containing mutations in the virus isolated at day 899 of infection. (D) Magnitude of the IFNγ+TNF+ CD4 or CD8 T cell response after 10-day in vitro peptide stimulation with individual epitopes using ancestral sequence or variant sequence peptides for culture and re-stimulation on day 9. Summary data showing all T cell responses that were detectable (left) or shown for individual peptides (right) for CD4 then CD8 T cells. Duplicate and triplicate stimulations are shown for CD8 T cells for M14 and NSP2, respectively. (D) Bars, mean. Statistical analysis was performed using Kruskal-Wallis tests with Dunn’s correction. ∗ p ≤ 0.05; ∗∗∗ p ≤ 0.001. Peptide sequences shown in .
