Background: Peripheral blood monocytes are key effectors of innate immunity. Dysfunction, changes in their counts or altered expression of cytokines and pattern-recognition receptors on monocytes may contribute to the development of the autoimmune type of diabetes mellitus (AD).

Aims: We aimed to analyze the counts and proportions of the two main subtypes of monocyte cells, CD14(++) and CD14(+), and to look for potential changes in the expression of toll-like receptors 2 (TLR2) and 4 (TLR4) as well as cytokine prolactin (PRL) in adult-onset AD, including diabetes mellitus type 1 (T1DM) and latent autoimmune diabetes in adults (LADA).

Psoriatic arthritis (PsA) affects approximately 30 % of patients suffering from psoriasis vulgaris (PsV), but the risk factors for its development have not been well elucidated yet. The HLA-Cw*06 allele was described as a predisposing factor to PsV. Prolactin is known as an immune response modulator, and its elevated levels present risk for PsV development.

The genetic components contribute to the systemic lupus erythematosus development. This study for the first time determined the distribution of the polymorphisms and linkage disequilibrium in HLA class II, MICA and PRL gene among patients suffering from SLE and healthy Czech individuals. DNA was obtained from the peripheral blood cells of 123 SLE patients and 96 healthy people.

Psoriatic arthritis (PsA) is a chronic inflammatory joint disease which affects patients suffering from psoriasis. The genetic background especially the susceptibility loci on the short arm of the chromosome six contribute to PsA development. In our study, we looked for the role of the MICA and HLA-Cw genes polymorphisms in PsA pathogenesis.

Type 1 diabetes with manifestation after 35 years of age is defined by CP <200 pmol/L and institution of insulin therapy within 6 months after diagnosis. Latent autoimmune diabetes mellitus in adults (LADA) manifesting after 35 years of age is defined by minimum 6 months after diagnosis without insulin therapy and C peptide (CP) >200 pmol/L and antiGAD > 50 ng/mL. We aimed to find a possible genetic discrimination among different types of autoimmune diabetes.

We have shown previously that amplification of chromosomal region 9q34 is the most frequent aberration in enteropathy-type T-cell lymphoma (ETL). To determine the minimum amplified 9q34 region and identify possible candidate gene(s), we performed a detailed microsatellite screening and quantitative real-time PCR (QPCR) on 26 ETL cases. Microsatellite analysis revealed allelic imbalance in both ABL1 and NOTCH1 gene loci (microsatellites D9S290-D9S1847 and D9S158 flanking the former and latter genes, respectively) localized in the band 9q34.

In our study, we investigated the relationship of HLA class II alleles to antibody production against glutamic acid decarboxylase (GADab) and to C-peptide secretion (CP) in diabetic patients. A group of 334 patients (190 women) diagnosed after 35 years of age and 99 control subjects were studied. Patients were divided into four groups according to concentrations of CP and GADab, respectively (CP high/low, GADab positive/negative).
