Abstract
Animal models of diabetes, such as db/db mice, are a useful tool for deciphering the genetic background of molecular changes at the initial stages of disease development. Our goal was to find early transcriptomic changes in three tissues involved in metabolism regulation in db/db mice: adipose tissue, muscle tissue and liver tissue. Nine animals (three per time point) were studied. Tissues were collected at 8, 12 and 16 weeks of age. Transcriptome-wide analysis was performed using mRNA-seq. Libraries were sequenced on NextSeq (Illumina). Differential expression (DE) analysis was performed with edgeR. The analysis of the gene expression profile shared by all three tissues revealed eight upregulated genes (Irf7, Sp100, Neb, Stat2, Oas2, Rtp4, H2-T24 and Oasl2) as early as between 8 and 12 weeks of age. The most pronounced differences were found in liver tissue: nine DE genes between 8 and 12 weeks of age (Irf7, Ly6a, Ly6g6d, H2-Dma, Pld4, Ly86, Fcer1g, Ly6e and Idi1) and five between 12 and 16 weeks of age (Irf7, Plac8, Ifi44, Xaf1 and Ly6a) (adj. p-value < 0.05). The mitochondrial transcriptomic profile also changed with time: we found two downregulated genes in mice between 8 and 12 weeks old (Ckmt2 and Cox6a2) and five DE genes between 12 and 16 weeks of age (Mavs, Tomm40L, Mtfp1, Ckmt2 and Cox6a2). The KEGG pathway analysis showed significant enrichment in pathways related to the autoimmune response and cytosolic DNA sensing. Our results suggest an important involvement of the immunological response, mainly cytosolic nucleic acid sensing, and mitochondrial signalling in the early stages of diabetes and obesity.

Abstract
The innate immune system recognizes pathogen-associated molecular motifs through pattern recognition receptors (PRRs) that induce inflammasome assembly in macrophages and trigger signal transduction pathways, thereby leading to the transcription of inflammatory cytokine genes. Nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs) represent a family of cytosolic PRRs involved in the detection of intracellular pathogens such as mycobacteria or viruses. In this review, we discuss the role of NOD1, NOD2, and NLRC5 receptors in regulating antiviral and antimycobacterial immune responses by providing insight into molecular mechanisms as well as their potential health and disease implications.

Abstract
Cytokine receptors are critical regulators of the antimycobacterial immune response, playing a key role in initiating and coordinating the recruitment and activation of immune cells during infection. They recognize and bind specific cytokines and are involved in inducing intracellular signal transduction pathways that regulate a diverse range of biological functions, including proliferation, differentiation, metabolism and cell growth. Due to mutations in cytokine receptor genes, defective signaling may contribute to increased susceptibility to mycobacteria, allowing the pathogens to avoid killing and immune surveillance. This paper provides an overview of cytokine receptors important for the innate and adaptive immune responses against mycobacteria and discusses the implications of receptor gene defects for the course of mycobacterial infection.

Abstract
Some intracellular pathogens are able to avoid the defense mechanisms contributing to host epigenetic modifications. These changes trigger alterations tothe chromatin structure and on the transcriptional level of genes involved in the pathogenesis of many bacterial diseases. In this way, pathogens manipulate the host cell for their own survival. The better understanding of epigenetic consequences in bacterial infection may open the door for designing new vaccine approaches and therapeutic implications. This article characterizes selected intracellular bacterial pathogens, including Mycobacterium spp., Listeria spp., Chlamydia spp., Mycoplasma spp., Rickettsia spp., Legionella spp. and Yersinia spp., which can modulate and reprogram of defense genes in host innate immune cells.

Abstract
Immunological memory is a key feature of adaptive immunity. It provides the organism with long-lived and robust protection against infection. The important question is whether cyclophosphamide (CP), as immunosuppressive agent used in cancer therapy and in some autoimmune diseases, may act on the memory T-cell population. We investigated the effect of CP on the percentage of central memory T cells (TCM) and effector memory T cells (TEM) in the mouse model of CP-induced immunosuppression (8-10-week-old male C57BL/6 mice CP treated for 7 days at the daily dose of 50 μg/g body weight [bw], manifested the best immunosuppression status, as compared to lower doses of CP: 10 or 20 μg/g bw). The CP induced a significant decrease in the percentage of CD8+ (TCM), compared to nonimmunosuppressed mice. This effect was not observed in the case of CD4+ TCM population. The percentage of gated TEM with CD4 and CD8 phenotype was significantly decreased in CP-treated mice, as compared to the control ones. Taken together, the above data indicate that CP-induced immunosuppression in mice leads to a reduction in the abundance of central memory cells possessing preferentially CD8+ phenotype as well as to a reduction in the percentage of effector memory cells (splenocytes both CD4+ and CD8+), compared to the cells from nonimmunosuppressed mice. These findings in mice described in this article may contribute to the understanding of the complexity of the immunological responses in humans and extend research on the impact of the CP model of immunosuppression in mice and memory T-cell populations.

Abstract
Dendritic cells (DCs) play a key-role in the immune response against
intracellular bacterial pathogens, including mycobacteria. Monocyte-derived
dendritic cells (MoDCs) are considered to behave as inflammatory cell
populations. Different immunomagnetic methods (positive and negative) can be
used to purify monocytes before their in vitro differentiation and their
culture behavior can be expected to be different. In this study we evaluated
the reactivity of two dendritic cell populations towards the Bacillus
Calmette-Gu?rin (BCG) antigen. Monocytes were obtained from the blood of
healthy donors, using positive and negative immunomagnetic separation
methods. The expression of DC-SIGN, CD86, CD80, HLA-DR and CD40 on MoDCs was
estimated by flow cytometry. The level of IL-12p70, IL-10 and TNF-? was
measured by ELISA. Neither of the tested methods affected the surface marker
expression of DCs. No significant alteration in immunological response,
measured by cytokine production, was noted either. After BCG stimulation, the
absence of IL-12, but the IL-23 production was observed in both cell
preparations. Positive and negative magnetic separation methods are effective
techniques to optimize the preparation of monocytes as the source of MoDCs
for potential clinical application.

Abstract
Mycolic acids are one of the basic structural elements of the cell wall of bacteria from Corynebacterineae suborder. These compounds are long-chain α-hydroxy β-alkyl fatty acids with two hydrocarbon chains: longer meromycolic and shorter α-chain meromycolic α-chain. The genus Mycobacterium is characterized by the presence of mycolic acids in length from 60 to 90 carbon atoms having a fully saturated α-chain with a defined length of 22, 24 or 26 carbon atoms. Current research indicates that not only the presence of mycolic acids in the cell wall of mycobacteria is essential for the virulence of mycobacteria. It is proved that the relationship between different types of mycolic acids, their length and the degree of cyclopropanation may vary depending on the stage of infection and mycobacterial culture conditions. At the same time it has been shown that some mycolic acid types are crucial for biofilm formation, antimycobacterial drug resistance or interactions with the immune system. Recent studies also indicate that analysis of mycolic acid profiles could be an alternative to conventional methods of diagnosis of diseases such as tuberculosis, leprosy or mycobacteriosis.

Abstract
The lysine connection with phosphatidylglycerol (PG) alters the M. tuberculosis(Mtb) surface charge, and consequently it may decrease the bacterial vulnerability to antimicrobial action of the immune cells. The aim of the study was to assess the significance of PG lysinylation in the Mtb interactions with mononuclear phagocytes. Both the Mtb strain with deletion of lysX gene (Mtb-lysX) which is responsible for PG lysinylation as well as the complemented strain (Mtb-compl) was used to infect human blood monocytes or THP-1 cells. The monocytes were obtained by MACS technique, or THP-1 cells. The Mtb-lysX strain has exhibited the enhanced sensitivity to HNP 1-3. However, it was not susceptible to bactericidal action of cathepsin G. The LysX deletion did not influence the Mtb ability of monocyte induction to IL-10 secretion. The intra- and extracellular expression of MHC-II was similarly reduced after the Mtb-lysX or Mtb-Rv infections. Noticeably significant is that the Mtb strain with deleted lysX has not affected the intensity of the gene expression of cathepsin G compared to the uninfected monocytes. That is the clear contrast to what the Mtb-Rv strain has proved. The obtained results suggest that the Mtb ability to lysinylate PG is a participatory element in mycobacterial strategy of survival inside phagocytic cells. However, the extended studies are needed to determine its influence on the other immune cells and define its role in the developing of Mtb infection.

Abstract
Mycolic acids are one of the basic elements of the cell wall structure of bacteria belonging to the suborder Corynebacterineae, constituting from 20% to 40% of dry weight. Additionally, they show high structural diversity within each family and species. Nowadays, profiles of mycolic acids are widely described for the genus Mycobacterium, the causative agent of tuberculosis. However, the suborder Corynebacterineae also includes many representatives of opportunistic human pathogens, e.g. Dietzia, Gordonia, Nocardia and Rhodococcus. Currently, an increased infection risk caused by this group of microorganisms especially in immunocompromised patients has been observed. Better knowledge of mycolic acid profiles for Corynebacterineae may allow identification of mycolic acids as diagnostic markers in the detection of opportunistic bacterial infections. Modern techniques of chemical analysis, including mass spectrometry, may enable the development of new chemotaxonomic methods for the detection and differentiation of bacteria within the suborder Corynebacterineae.

Abstract
One third of the earths population is infected with Mycobacterium tuberculosis (Mtb), but only 5-10% of the infected individuals develop active tuberculosis (TB) over their lifetime. The remaining 90-95% stay healthy and are called latently infected individuals. They are the biggest reservoir of the tubercle bacilli and identifying the cases of latent TB is a part of the global plan of TB control. From the clinical point of view detection of latent TB infections (LTBI) in individuals with the highest active TB risk including cases of HIV infection, autoimmune inflammatory diseases or cancer, is a priority. This review summarizes the recent findings in the pathogenesis of latent TB, its diagnosis, treatment and prevention.

Abstract
Mycobacterium is a variable group of acid-fast bacillus which contains pathogenic bacteria causing tuberculosis (MTC - Mycobacterium tuberculosis complex) and leprosy (M. leprae) as well as numerous nontuberculous mycobacteria (NTM) causing diseases mostly in people with immunodeficiency, although some NTM strains are capable of causing illnesses in non-immunocompromised patients. This group includes for example Mycobacterium marinum, Mycobacterium ulcerans and Mycobacterium xenopi. These microorganisms are environmental mycobacteria, present in developing countries of Africa, but they may also be transferred to other continents. The most common symptoms of diseases caused by these species are skin lesions (hyperpigmentation, tumors, ulcers) and arthritis. Because of the rarity of their occurrence, these mycobacteria are relatively poorly known. Effective ways of treating the diseases caused by these bacilli are still under study.

Abstract
One third of the earth's population is infected with Mycobacterium tuberculosis, but only 5-10% of the infected individuals will develop active disease over their lifetime. To identify the genes responsible for the variation in the human susceptibility/resistance to tuberculosis (TB) we determined the polymorphisms of three genes crucial for the function of macrophages, in TB patients and healthy controls with no past history of TB. We found no association between the polymorphisms of the NRAMP-INT4, MBL (codons 52, 54, 57) and CD14-159 genes and TB in a Caucasian Polish population. However, we have suggested a possible involvement of CD14 and MBL molecules in the host-mycobacteria interactions on the basis of the significant increase in the serum CD14 and MBL in TB patients compared to healthy controls.

Abstract
The polarized response of T helper-2 (Th2) lymphocytes to an allergen is considered to be the main cause of the pathogenesis of asthma. In this study, we asked a question whether M. bovis BCG mycobacteria which are known for the preferential stimulation of T helper-1 (Th1) immunity, diminish the effector functions of Th2 cells from allergic patients upon stimulation with a common house dust mite Der p-1 allergen. Our results allow a positive answer to this question. We demonstrate that BCG modulates the dendritic cell-dependent allergen presentation process and switches naive T lymphocytes towards an anti-allergic Th1 profile.

Abstract
In this study we asked a question whether H. pylori LPS with or without LewisXY (Le) determinants as well as LBP (lipopolysaccharide binding protein) and sCD 14 molecules recognizing bacterial LPS may be involved in atherogenesis. Sera from 57 patients with coronary heart disease (CHD), 27 H. pylori infected dyspeptic patients-H.p.(+) and 49 healthy controls (HC) were tested for IgM and IgG to H. pylori LPS expressing LeX (LPS LeX) or LeXY (LPS LeXY) determinants and to a glycine acid extract (GE). Immune complexes (ICs) of Lewis antigens and specific IgM or IgG were also determined. The prevalence of anti-GE IgG and IgA was significantly higher in CHD as compared to HC and the same as in the H.p.(+) group. The highest levels of anti-GE IgG were detected only for CHD group. CHD patients showed upregulation of IgG to LPS LeX and LeXY. In contrast, an upregulation of IgM to such LPSs was found for healthy subjects. The levels ofLeY-anti-LeY IgG ICs were higher in CHD patients than in healthy controls similarly to the levels of LBP. There was no difference in sCD14 concentration between CHD and HC groups. The results obtained in this study indicate that H. pylori infections may be the risk factors of atherosclerosis due to: 1) an enhanced humoral response to H. pylori surface antigens, 2) a host predisposition to respond to Lewis determinants present in H. pylori LPS by IgG, 3) increased levels of serum LBP.
