The paper contains an overview of the role of certain minor subpopulations of lymphocytes in tumour growth and of the main results obtained in the studies of the phenotype of immunocompetent cells from cancer patients. Special attention is given to selected indicators of immunity as predictors of the disease and efficacy of immunotherapy.

Glioblastomas (GBMs) are the most common and aggressive brain tumors, with a poor prognosis. Effective preclinical models are crucial to investigate GBM biology and develop novel treatments. Syngeneic models, which consist in injecting murine GBM cells into mice with a similar genetic background, offer reproducibility, cost-effectiveness, and an intact immune system, making them ideal for immunotherapy research.

Orthoflaviviruses are emerging arthropod-borne pathogens whose replication cycle is tightly linked to host lipid metabolism. Previous lipidomic studies demonstrated that infection with the closely related hepatitis C virus (HCV) changes the fatty acid (FA) profile of several lipid classes. Lipids in HCV-infected cells had more very long-chain and desaturated FAs and viral replication relied on functional FA elongation and desaturation.

Hemolymph enables communication between organs in insects and ensures necessary coordination and homeostasis. Its composition can provide important information about the physiological state of an insect and can have diagnostic significance, which might be particularly important in the case of harmful insects subjected to biological control. Linnaeus 1758 (Lepidoptera: Pyralidae) is a global pest to honey bee colonies.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is considered a "cold" tumor because the tumor immune microenvironment (TIME) exhibits poor intratumoral T-cell infiltration. This study aimed to identify the marker genes associated with induction of cold TIME in PDAC cells.
Methods: We orthotopically transplanted 10 primary cultures of PDAC derived from KrasG12D/+; Trp53R172H/+; Pdx-1-Cre (KPC) mice into immunocompetent mice and evaluated TIME by immunohistochemistry (IHC) staining of CD8.
Chlamydia muridarum Causes Persistent Subclinical Infection and Elicits Innate and Adaptive Immune Responses in C57BL/6J, BALB/cJ, and J:ARC(S) Mice Following Exposure to Shedding Mice.

Chlamydia muridarum (Cm) has reemerged as a moderately prevalent infectious agent in research mouse colonies. Despite its experimental use, few studies evaluate Cm's effects on immunocompetent mice following its natural route of infection. A Cm field isolate was administered (orogastric gavage) to 8-wk-old female BALB/cJ (C) mice.
