For the first time we tried to examine the basic parameters of innate immunity in beavers for developing the new methods of prevention against infectious diseases in different reintroduction and translocation programmes in Poland. The aim of the present study was to determine the selected innate immunity parameters in Eurasian beavers living in natural conditions. The analyses of the results showed that the phagocytic ability (RBA) and potential killing activity (PKA) of blood phagocytes were higher in adult beavers compared to the young animals. The similar pattern was observed in proliferative response of blood lymphocytes stimulated by mitogens Concanavalin A (Con A) and lipopolysaccharides (LPS). The highest proliferative response in adult Eurasian beavers was observed. The ceruloplasmin activity in plasma was on similar levels in adult and young Eurasian beavers. The results of humoral mediated immunity showed that the lysozyme activity, total protein and gamma-globulin levels in serum were higher in adult beavers compared to the young beavers. The results of this preliminary study are important in comparative and clinical immunology.

Viruses have evolved to strategically exploit cellular signaling pathways to evade host immune defenses. GM-CSF signaling plays a pivotal role in regulating inflammation, activating myeloid cells, and enhancing the immune response to infections. Due to its central role in the immune system, viruses may target this pathway to further establish infection.

Virus-host protein interaction is critical for successful completion of viral replication cycles. As the largest nonstructural protein (NSP) of porcine reproductive and respiratory syndrome virus (PRRSV), NSP2 plays multiple and critical roles in viral replication, antiviral immunity, cellular tropism and virulence. An interactome of this protein with host proteins would be instrumental in full understanding of these multifunctional roles.

Obesity is a chronic inflammatory disease that affects more than 1 billion people worldwide and is associated with various metabolic and physiological dysfunctions, directly impacting the dynamics of the immune response, partly due to elevated leptin levels. Leptin is an important peptide hormone that regulates neuroendocrine function and energy homeostasis, with its blood levels reflecting energy reserves, fat mass, or energy deprivation. This hormone also plays a fundamental role in regulating immune function, including the activity of NK cells, which are essential components in antiviral and antitumor activity.

The accurate assembly of the ribonucleoprotein (RNP) complex is fundamental for the replication and transcription of rhabdoviruses, which are known for their broad pathogenic impact. A novel 119-amino-acid protein, NLRP12-119aa is identified, encoded by the circular RNA circNLRP12, that effectively disrupts the formation of rhabdovirus RNP complexes through two distinct mechanisms and significantly reduces their replication. NLRP12-119aa exhibits a strong affinity for the conserved 18-nucleotide sequence at the start of the leader RNA of rhabdoviruses VSV, SCRV, and RABV, outcompeting their native N protein interactions, thereby disrupting the assembly of RNP complexes and inhibiting viral replication.
