The practical problems that call for solution are to ensure that a kidney transplant is not rejected by the immune response or to accentuate an inadequate immune attack on a malignant tumour . They require a deeper probe into the uncanny capacity of the body to recognise the intrusion of material foreign to itself , be it a virus , bacterium , cell or whatever , and to mobilise cells and cell products to help remove that particular sort of intruder with greater speed and effectiveness . जिन व्यावहारिक प्रश्नों के उत्तर ज्ञात करने के लिए प्रयास किये जा रहे हैं उनमें गुर्दे के प्रतिरोपणा के पश्चात शरीर द्वारा उसे अस्वीकार किया जाना तथा कैंसरीय ट्यूमर प्रतिरक्षा के दौरान किये जाने वाले हमलों को तीव्र बनाना सम्मिलित हैं .
