Abstract

This study was undertaken to identify the distribution of T and B lymphocytes in bovine peripheral blood and various lymphoid tissues by the method of ABPC using RABTS, $BLT_1$ and $_6E_{12}$ as primary antibodies. RABTS, $BLT_1$ and $_6E_{12}$ positive cells in PB-MNCs were 70.9${\pm}5.5%$, $59.0{\pm}8.7%$ and $23.0{\pm}8.7%$, respectively. $BLT_1$ and $_6E_{12}$ positive cells in nylon wool nonadherent cells of PB-MNCs were $91.6{\pm}1.0%$ and $9.6{\pm}0.8%$, respectively. In the lymphoid tissues such as inguinal lymph node, mesenteric lymph node, spleen and thymus, positive cells of RABTS were $76.3{\pm}3.4%$, $74.2{\pm}8.2%$, $73.6{\pm}5.5%$ and $95.6{\pm}2.8%$, those of $BLT_1$ were $56.4{\pm}6.2%$, $55.6{\pm}7.7%$, $48.6{\pm}5.1%$ and $23.0{\pm}4.8%$ and those of $_6E_{12}$ were $45.3{\pm}7.4%$, $42.3{\pm}5.8%$, $48.5{\pm}6.2%$ and $5.6{\pm}2.1%$, in order. These results are indicating that nylon wool column method is effective for separation of bovine ocytes.

소의 순환혈액 및 림프조직내의 T 및 B 림프구의 분포를 파악하고자 소흉선 세포를 토끼에 과면역시켜 얻은 항혈청을 소의 적혈구, 간장분말 및 골수세포에 순차적으로 흡착시킨 항 흉선 세포혈청(RABTS)과 성숙 T 림프구에만 특이성을 가진 단클론항체 $BLT_1$ 및 B 림프구와 소수의 대식세포에 특이성을 가진 단클론항체 $_6E_{12}$를 1차 항체로 이용하여 ABPC법으로 T 및 B 림프구를 동정한 바 다음과 같은 결과를 얻었다. RABTS 및 $BLT_1$으로 동정한 순환혈액내 단핵세포(PB-MNCs) 중 T림프구의 비율은 각각 70.9${\pm}5.5%$$59.0{\pm}8.7%$이었으며, PB-MNCs중 nylon wool 비부착세포를 $BLT_1$$_6E_{12}$로 동정한 T 및 B 림프구의 비율은 각각 $91.6{\pm}1.0%$, $9.6{\pm}0.8%$이었다. 또한 $BLT_1$$_6E_{12}$로 동정한 서혜림프절, 장간막 림프절, 비장 및 흉선의 T/B림프구의 비율은 각각 $56.4{\pm}6.2/45.3{\pm}7.4%$, $55.6{\pm}7.7/42.3{\pm}5.8%$, $48.6{\pm}5.1/48.5{\pm}6.2%$$23.0{\pm}4.8/5.6{\pm}2.1%$이었으며, RABTS로 동정한 이들 림프조직내의 T림프구의 비율은 각각 $76.3{\pm}3.4%$, $74.2{\pm}8.2%$, $73.6{\pm}5.5%$$95.6{\pm}2.8%$이었다. 이상의 결과로 미루어 PB-MNCs네의 T림프구 분리는 nylon wool column법이 보다 효과적임을 알 수 있었다.
