We have recently shown that interleukin-9 (IL-9) strongly stimulates the proliferation of mouse thymic lymphomas in vitro. Here we report that this factor is also one of the most potent inhibitors of apoptosis induced by dexamethasone (DEX) in such cell lines, even if they do not depend on exogenous factors for growth. For the murine thymic lymphoma BW5147, protection against apoptosis was also...

Human natural killer INK) cells are large granular lymphocytes that constitutively express functional forms of the interleukin-2 receptor (IL-2R) and lyse tumor and virally infected cells without prior sensitization. NK cells with high density expression of CD56 (CD56b'ieh') express the high affinity IL-2R and proliferate in response to low (picomolar) concentrations of IL-2. CD56d'm NK cells e...

imbalanced immune responses against fetus alloantigens can lead to abnormality in pregnancy. interleukin-10(il-10) plays key roles in regulation of immune responses against self and foreign antigens to induce tolerance to these antigens. therefore, alteration in expression of il-10 during pregnancy may result in several pathologic conditions such as preterm labor. il-10 leads to a normal pregna...

AbstractPentavalent antimonials, as the 1st choice for the treatment of cutaneous leishmaniasis (CL), have various side effects. Also, there are some reports of drug resistance.
