Characterization of Platelet Receptors and Their Involvement in Immune Activation of These Cells.

The article characterises platelets, pointing out the role and contribution of their numerous receptors determining their specific and broad immune activity. Three types of platelet receptors are described, that is, extracellular and intracellular receptors-TLR (toll-like receptors), NLR (NOD-like receptor), and RLR (RIG-I-like receptor); extracellular receptors-selectins and integrins; and their other extracellular receptors-CLR (C-type lectin receptor), CD (cluster of differentiation), TNF (tumour necrosis factor), among others. Outlining the contribution of these numerous platelet receptors to the intravascular immunity, it has been shown that they are formed by their fusion with pathogen-associated molecular patterns (PAMPs), damage-associated molecular patterns (DAMPs), and lifestyle-associated molecular patterns (LAMPs).

Preliminary proteomic analysis of mouse lung tissue treated with cyclophosphamide and Venetin-1.

Cyclophosphamide (CPAm) is a widely used chemotherapeutic agent that exhibits potent anti-cancer properties but is often associated with debilitating side effects. Despite its efficacy, the management of CPAm-induced toxicities remains a significant clinical challenge. There has been growing interest in exploring complementary and alternative therapies to mitigate these adverse effects in recent years, and this may be a chance for the earthworm-derived preparation, Venetin-1.

Virophages, Satellite Viruses, Virophage Replication and Its Effects and Virophage Defence Mechanisms for Giant Virus Hosts and Giant Virus Defence Systems against Virophages.

In this paper, the characteristics of 40 so far described virophages-parasites of giant viruses-are given, and the similarities and differences between virophages and satellite viruses, which also, like virophages, require helper viruses for replication, are described. The replication of virophages taking place at a specific site-the viral particle factory of giant viruses-and its consequences are presented, and the defence mechanisms of virophages for giant virus hosts, as a protective action for giant virus hosts-protozoa and algae-are approximated. The defence systems of giant viruses against virophages were also presented, which are similar to the CRISPR/Cas defence system found in bacteria and in Archea.

Characterisation of GI-RHDVs (Rabbit Haemorrhagic Disease Viruses) in Terms of Their Pathogenicity and Immunogenicity.

Rabbit haemorrhagic disease viruses (RHDV) belong to the family genus , genogroup GI, comprising four genotypes GI.1-GI.4, of which the genotypes GI.

Innate lymphoid cells (ILCs) in teleosts against data on ILCs in humans.

It is assumed that cells corresponding to innate lymphoid cells (ILCs) in humans, in addition to lymphoid tissue inducer cells (LTi), are also found in teleosts. In this systematic group of organisms, however, they are a poorly understood cell population. In contrast to the data on ILCs in humans, which also remain incomplete despite advanced research, in teleosts, these cells require much more attention.
