Sažetak
Serotonin (5-hydroxytryptamine, 5-HT) has been shown to play a role in immunoregulation; however, little is known about specific subtypes of 5-HT receptors involved in peripheral immunomodulation. In the present study we used RT-PCR methods to examine the mRNA expression of 5-HT receptors in the cells of lymphoid tissues of the rat. All thirteen rat 5-HT receptor genes cloned so far were examined in ex vivo isolated spleen, thymus and peripheral blood lymphocytes, as well as in mitogen stimulated spleen cells. Positive signals were obtained for 5-HT1B, 5-HT1F, 5-HT2A, 5-HT2B, 5-HT6 and 5-HT7 receptor mRNAs in all three compartments. Mitogen (ConA and PWM) stimulated spleen cells additionally expressed mRNA corresponding to the 5HT-3 receptor subtype. In contrast, 5-HT1A, 5-HT1D, 5-HT2C, 5-HT4, 5-HT5A and 5-HT5B mRNAs were not detected in any of the examined cell populations. These results may be useful as a starting point for future functional studies on immunomodulatory effects of 5-HT, and may help to understand conflicting serotonergic effects on immune functions as found in the literature.
