The relationship between cell-mediated immunity and alcohol intake was studied in an Antarctic wintering group. Cell-mediated immune responses have previously been shown to be significantly lowered on the Antarctic Continent. The cause for this is yet to be elucidated. The cutaneous CMI Multitest was used to assess cell-mediated immunity. Carbohydrate deficient transferrin (CDT) was used to assess chronic alcohol consumption and acute consumption was self-reported. Results showed a significantly elevated incidence of anergy when compared with previous results (53 v. 6.5%). The incidence of hypoergy was similar to previously reported levels (34%). There was no relationship demonstrated between both acute or chronic alcohol consumption and levels of cell-mediated immunity using the Spearman Rank Correlation Coefficient. There was also no correlation found between CDT and self-reported alcohol intake. It is concluded that factors other than alcohol are responsible for the decrease in cell-mediated immunity in Antarctic wintering personnel.

KSHV hijacks the antiviral kinase IKKε to initiate lytic replication.

IKKε is a traditional antiviral kinase known for positively regulating the production of type I interferon (IFN) and the expression of IFN-stimulated genes (ISGs) during various virus infections. However, through an inhibitor screen targeting cellular kinases, we found that IKKε plays a crucial role in the lytic replication of Kaposi's sarcoma-associated herpesvirus (KSHV). Mechanistically, during KSHV lytic replication, IKKε undergoes significant SUMOylation at both Lys321 and Lys549 by the viral SUMO E3 ligase ORF45.

In plants, cytoskeletal proteins assemble into dynamic polymers that play numerous roles in diverse fundamental cellular processes, including endocytosis, vesicle trafficking, and the spatial distribution of organelles and protein complexes. Plant elicitor peptides (Peps) are damage/danger-associated molecular patterns (DAMPs) that are perceived by the receptor-like kinases PEP RECEPTOR 1 (PEPR1) and PEPR2 to enhance innate immunity and inhibit root growth in Arabidopsis (Arabidopsis thaliana). To date, however, there is little evidence that the actin cytoskeleton of the host cell participates in DAMP-induced innate immunity.

Recombinant adeno-associated virus (rAAV) has emerged as one of the best gene delivery vectors for human gene therapy in vivo. However, the clinical efficacy of rAAV gene therapy is often hindered by the host immune response against its transgene products. Endoplasmic reticulum aminopeptidase 1 (ERAP1) is specialised to process peptides presented by class I molecules of major histocompatibility complex.

X-linked severe combined immunodeficiency disease (X-SCID) is a form of inborn errors of immunity (IEI) associated with causal DNA variants of the gene. Patients with X-SCID are characterized by a combination of cellular and humoral immunodeficiencies associated with increased susceptibility to infections. The presented cases constituted two unrelated male patients from the Slovak population.

Allergen-specific immunotherapy (AIT) is the only treatment that addresses the root cause of immunoglobulin E (IgE)-mediated allergies, but conventional methods face challenges with treatment duration, patient compliance, and adverse effects. In this study, we propose intratonsillar immunotherapy (ITIT) as a new effective and safer route for AIT. Prior to clinical trials, we analyzed tonsil samples from human subjects to assess immune responses, measuring interleukin-4 (IL-4), IL-21, total IgE (tIgE), and allergen-specific IgE concentrations using ELISA and BioIC.
