                    34.  A method of inhibiting signal transduction in tumor necrosis factor receptors                
             (TNF-Rs), comprising:                                                                                    
                    identifying a molecule which binds to the portion of TNF-R which includes Ser197 or               
             the amino acids 405 to 415 of human p55-TNF-R (SEQ ID NO:2) or the corresponding                         
             amino acids of the human p75-TNF-R, and thereby causes the signal transduction of said                   
             receptor to be inhibited; and                                                                            
                    bringing said molecule into contact with said portion of TNF-R.                                   
                    37.  A method for identifying molecules which interact with TNF-R to modulate                     
             signal transduction by the TNF-R, comprising:                                                            
                    a)  preparing a target peptide which includes amino acids 405-415 of human p55-                   
             TNF-R (SEQ ID NO:2) or the corresponding amino acids of human -75-TNF-R;                                 
                    b)  screening peptide libraries and/or broth of biological matter with said target                
             peptide and identifying any molecules which bind to said target peptide; and                             
                    c)  screening any molecules identified in step b) for their ability to modulate signal            
             transduction of TNF-R and identifying any molecule which tests positive for such signal                  
             transduction modulation.                                                                                 

                    42.  A method of inhibiting signal transduction in tumor necrosis factor receptors                
             (TNS-Rs), comprising:                                                                                    
                    identifying a molecule which reacts with TNF-R to modulate signal transduction by                 
             the TNF-R, by means of a process in accordance with claim 37; and                                        
                    bringing said molecule into contact with the portion of TNF-R which includes amino                
             acids of human p75-TNF-R.                                                                                

                    43.  A method in accordance with claim 37, for identifying a molecule which                       
             interacts with TNF-R to inhibit signal transduction by the TNF-R, wherein said step c)                   
             comprises screening any molecules identified in step b) for their ability to inhibit signal              
             transduction of TNF-R and identifying any molecule which tests positive for such signal
