Electronic cigarettes (e-cigarettes) were introduced two decades ago as a safer alternative to traditional cigarettes, aiming to assist in smoking cessation. However, the global use of e-cigarettes has surged, with the highest prevalence among adolescents and young adults. Despite their popularity, the safety of e-cigarettes remains controversial, with emerging evidence linking their use to various health risks, including cardiovascular issues, respiratory diseases, and a condition known as e-cigarette or vaping use-associated lung injury (EVALI).

Human γδ T cells are divided into 5 major subsets, namely Vδ1-Vδ5, of which the latter 3 have limited available literature. At present, Vδ2 is the most studied subpopulation.

The relation of Gal-9 expression in malignant B-cells and other routinely measured CLL markers, as well as its clinical relevance are poorly understood. Gal-9 mRNA expression was quantified with RT-qPCR in purified CD19+ B-cells of 100 CLL patients and analyzed in the context of existing clinical data.

They are capable of rapid cytokine production after the initial stimulus, thus they may be important for polarisation of Th cells. Due to this, they may be an important cell subset in autoimmune diseases.

Numerous studies have demonstrated that using electronic cigarettes may lead to nicotine dependence and has a potentially harmful impact on health. The present study compared the impact of electronic and conventional cigarettes on lung tissue.

Background: Smoking is frequently a way to control appetite and weight. The data concerning the body mass gain after quitting among the users of electronic cigarettes who have no prior history of smoking traditional cigarettes is inconsistent.
Objective: In our study we have compared smoking and vaping impact on weight gain and glycaemia.
The aim of the current study is to evaluate IL-17 production and RORγT, and IL-23R expression by iNKT, Th17 and γδ T cells in the peripheral blood of relapsing-remitting multiple sclerosis patients. Samples of peripheral blood from 21 relapse patients and 12 remission patients, and 15 healthy volunteers were stained with monoclonal antibodies for flow cytometry analysis. No significant differences in iNKT, γδ T and Th17 percentages were noted.

The aim of this paper was to summarise knowledge of IL-22 involvement in multiple sclerosis (MS) and the possible link between IL-22 and two transcription factors - AHR and c-Maf. The conclusion is that despite numerous studies, the exact role of IL-22 in the pathogenesis of MS is still unknown. The expression and function of c-Maf in MS have not been studied.

Despite the fact that numerous studies have been performed, the role of γδ T is still not fully understood. It seems that there are two distinct subpopulations - one exacerbating the disease (IL-17-producing) and the other playing a protective role (IFN-γ-secreting).

Introduction: Nicotine stimulates fibroblast proliferation while increasing inflammation and fibrosis of tissues. The cannabinoid receptor 1 (CB1R) is mainly located in the CNS, while cannabinoid receptor 2 (CB2R) is located in the immune cells within the body. CB2R regulates inflammatory processes and fibroblast function.

Anti-vaccination movement has existed as long as the vaccines themselves, but its mode of action and social influences evolved over time. Such attitude with no doubt has negative impact on vaccination rates and eradication of infectious diseases. In this study, we used an online survey to examine vaccination attitudes of Polish university students of various degree and specialties.

E-cigarettes are highly advertised across the media, mainly as healthy substitute to conventional cigarettes, aid in quitting smoking addiction or way of circumventing ban on smoking in public places.
Objective: The aim of study was obtaining epidemiological data on cigarette smoking and electronic cigarette usage among Polish universities students.
