Opis:
The activity of IgG, IgM and IgE antibodies to somatic antigen of Trichinella spiralis in the sera of patients with trichinellosis at various intervals after infection was examined by means of ELISA. Mathematical analysis of the dose-response curves was used. Elevated level of IgG and IgM antibodies of relatively high avidity and of rather low IgE avidity was documented. Amount or avidity ofIgG antibodies was found to be most useful for the diagnosis of trichinellosis (85% positive results in patients' sera). The isotype of IgM avidity constitutes a better diagnostic value than the amount of it (60% and 35% of positive results, respectively).

Opis:
The honeybee developed through evolution efficient inborn and acquired immune mechanisms which allow it to function in the enviromment. In the inborn immunity phagocytosis is classified to the oldest defensive mechanisms which relies on catching and destruction of the pathogens by the plastmocytes and granulocytes in the hemolymph and lysozymes – the most important components of the natural humoral immunity. Acquired immunity covers, above all, polypeptides and immune proteins e. g. apidaecin and abbacin. Apidaecins represent one of the most important anti-bacterial elements of acquired immunity. Apidaecins arise from fat bodies appearing soon after bacterial infection, also protect the insect from envirommental pathogens. Abaccin acts mainly on Gram positive bacteria. Its characteristic quality is delayed action in camparision to apidaecins, synergy with bee hemolymph anti-bacterial factors as well as assistance in anti-bacterial defense.

Opis:
B6C3F₁ mice were infected with 200 or 500 larvae of Trichinella spiralis per mouse and pulmonary NK cell-mediated clearance of semisyngeneic tumour cells was determined in vivo on days 10, 20, 30, and 60 after the infection. Cytotoxic activity of NK cells in the lungs was substantially elevated on days 20 and 30 after challenge with both „doses" of the parasite. At the same time large granular lymphocytes (LGLs) as well as cells expressing surface asialo-GM₁ molecules were isolated in elevated numbers from spleens of the infected as opposed to the normal mice. Expression of other markers of differentiation, such as THy 1, CD4, and CD8 was also enhanced on splenocytes isolated from the infected mice on day 30 but not 20 after administration of the larvae. The present results indicate that NK cell-mediated activity in vivo is stimulated above the baseline level during migration and early muscle phases of the infection with T. spiralis in mice. The possible impact of this effect upon the course of trichinellosis as well as upon the growth of tumours in the infected host is discussed.

Opis:
This paper presents the development of novel liposomal nanocarriers which can be used in delivery of biologically-active substances, such as proteins. There is a great interest in liposomal carriers, which could be used for medical and pharmacological applications. However, because of low stability of liposomes, such applications are challenging. Certain external factors, such as pH, temperature or the presence of other substances in the environment may have a damaging effect on the lipid vesicles. Proteins are known to play an essential role in the functioning of living organisms. They have mechanical-structural functions, but they can also act as biocatalysts (enzymes), neurotransmitters, or are involved in the transport of small molecules and ions in tissue. The interest in GPI-linked proteins is related to their ability to incorporate in the lipid bilayer. They have a glycosylphosphatidylinositol anchor with two long alkyl chains. These chains can incorporate in the cell membrane, thus allowing their attachment to the outer surface of vesicles. Coating them with polyelectrolytes can increase the stability of liposomes. It was found that some polymeric films have the ability to stabilize the liposomal nanocarriers of proteins. That can be correlated with the value of the zeta potential of polymer which coats liposomes, as well as with the shape of a polymeric chain. The polymeric coating can be carefully chosen to ensure that the stabilizing effect will be associated with protein protection reflected in its high enzymatic activity.
